Bleaching powder is chemically calcium oxychloride which contains chlorine as its key component. It is produced by passing chlorine gas over dry slaked lime. Bleaching powder is widely used as a disinfectant for drinking water as a bleaching agent in the textile and paper industries and for cleaning purposes. The chlorine present in bleaching powder is responsible for its ability to kill bacteria and viruses. Although effective it must be handled carefully because high concentrations can be harmful. It represents one of the earliest industrial applications of chlorine and continues to play a vital role in sanitation.

An ionic bond forms when electrons are transferred from one atom to another leading to positively and negatively charged ions. For example sodium donates an electron to chlorine forming sodium chloride. The electrostatic force between the oppositely charged ions holds them together strongly in a crystalline structure. Ionic bonds are generally formed between metals and nonmetals and they have high melting and boiling points. Compounds with ionic bonds often dissolve in water and conduct electricity in molten or dissolved states. This type of bonding plays a key role in chemistry and biological processes where ionic interactions are important.

The relationship between gas pressure and volume is explained by Boyle law which states that at constant temperature the pressure of a gas is inversely proportional to its volume. This means that if pressure is increased the volume decreases and if pressure is reduced the volume expands. In a cylinder filled with gas applying more pressure compresses the particles into a smaller space. This principle is widely used in compressors aerosol sprays and industrial gas storage. Understanding this concept is important in fields such as physics chemistry and engineering because it applies to many real life systems and technologies.

Cobalt 60 is a radioactive isotope that emits powerful gamma rays. These rays can penetrate deep into human tissues and are used in radiotherapy machines to target and destroy cancer cells. Gamma rays damage the DNA of cancerous cells preventing them from dividing and spreading. At the same time doctors use focused doses to minimize harm to surrounding healthy tissues. Cobalt 60 therapy has been one of the most effective treatments for various cancers. It remains a cost effective and reliable option in many countries where advanced linear accelerators are not available making it vital in oncology treatment.

Carbon 14 has a half life of about 5730 years which makes it useful for radiocarbon dating. This technique is applied in archaeology geology and environmental science to determine the age of ancient organic materials. By measuring the amount of carbon 14 remaining in samples like wood bones or shells scientists can estimate how long ago the organism died. Because the half life is long carbon 14 dating is effective for artifacts up to about 50000 years old. It has revolutionized our understanding of history and prehistoric life giving researchers a powerful tool to study ancient civilizations.

Photocopier machines and laser printers often produce small amounts of ozone gas during operation. This occurs because high voltage electrical discharges inside the machine split oxygen molecules creating ozone. In low concentrations ozone has a sharp smell and can be irritating to the eyes nose and throat. In high concentrations it can be harmful to health and damage lung tissue. For this reason photocopiers are usually placed in ventilated rooms to avoid buildup of ozone. Despite the risk modern machines are designed with filters and technology to reduce ozone emissions. Therefore ozone is the gas released in photocopying machines.

The left atrium of the human heart is the chamber that receives oxygenated blood. Oxygenated blood comes from the lungs through the pulmonary veins. From the left atrium the blood is pushed into the left ventricle which pumps it to the whole body through the aorta. This process is vital because the body requires a constant supply of oxygen to survive. The right side of the heart deals with deoxygenated blood while the left side manages oxygen rich blood. Understanding the role of each chamber helps in studying human physiology and diseases like heart failure and valve problems.

The least count of Vernier Calliper is 0.1 millimeter which means it can measure lengths with accuracy up to one tenth of a millimeter. Least count is defined as the smallest measurement that an instrument can read. Vernier Calipers are widely used in laboratories engineering workshops and industries for accurate measurement of internal and external diameters depth and thickness. This high level of precision makes the Vernier Calliper essential in fields where exact dimensions matter. Its design combines a main scale and a sliding Vernier scale which allows users to measure more accurately than a simple ruler.

The scientific name of the common frog found in South Asia is Rana Tigrina which is also known as Hoplobatrachus tigerinus. It belongs to the class Amphibia which includes animals that can live both on land and in water. Frogs play an important role in the ecosystem as they help control insect populations and serve as prey for birds and reptiles. They are also considered bio indicators because their presence or absence indicates the health of an environment. Rana Tigrina has strong hind legs that help it jump and swim efficiently making it well adapted for survival in wet habitats.

Potential energy is the energy stored in an object due to its position shape or condition. For example a stone held at a height has potential energy because of gravity. When released the stone falls and the energy converts into kinetic energy. Another example is a stretched spring or a charged battery which both store energy that can be released later. Potential energy is a key concept in physics as it explains how energy is conserved and transformed between different forms. It plays an important role in machines buildings vehicles and natural systems like rivers waterfalls and mountains.

The cell wall of plant cells is mainly formed of cellulose which is a carbohydrate polymer. Cellulose molecules form strong fibers that give rigidity and support to the plant cell. The cell wall not only provides structure but also protects cells against mechanical stress and pathogens. It also helps regulate water intake and prevents excessive expansion of cells. In addition to cellulose plant cell walls may contain hemicellulose and lignin depending on the plant type. Humans cannot digest cellulose but it is important in the diet as dietary fiber. Cellulose is also widely used in paper textile and biofuel industries.

Brass which is an alloy of copper and zinc gets discoloured in air due to the presence of hydrogen sulphide gas. When hydrogen sulphide comes in contact with brass it reacts with copper to form copper sulphide which is black in color. This chemical reaction creates a tarnished layer on the surface of brass. Over time the shine of brass decreases and it looks dull. This process is called tarnishing and is common for copper and brass materials. To prevent tarnishing brass objects are polished regularly or coated with protective layers. Therefore hydrogen sulphide gas is the main cause of discoloration.

Desktop computers are not considered portable devices because they are large and require external power sources. In contrast laptops thumb drives and iPods can easily be carried and used in different locations. Portability is an important feature for modern technology because users need access to data and applications while moving from place to place. Devices like laptops combine power and mobility allowing people to work study or entertain themselves anywhere. Thumb drives and iPods are examples of small devices that provide convenience for data transfer and media use. Thus desktops are stationary systems while others are portable.

The printed output from a computer is called a hardcopy. It is produced by devices like printers or plotters. A hardcopy provides a permanent physical record of data images or documents. For example printed reports books or invoices are all hardcopies. In contrast a soft copy is displayed on a screen and can be edited easily. Hardcopies are often required for official records legal documents and contracts because they are less vulnerable to accidental changes. Although digital storage is popular hardcopies remain important in many industries for reliability authenticity and convenience. Thus the correct option is hardcopy.

Getting data from a cell located in another worksheet within the same file is called referencing. For example in Microsoft Excel if you want to use the value from Sheet2 cell A1 in Sheet1 you can write the formula =Sheet2!A1. Referencing is important because it helps in linking data across multiple sheets without the need to duplicate information. It ensures accuracy efficiency and consistency in large spreadsheets. This method is widely used in finance accounts data analysis and project management where values from multiple sheets need to be combined for calculations reports and decision making.

The Edit > Delete command of a cell is used to delete the selected cells themselves not just their content or formatting. When this command is applied the neighboring cells shift to adjust the space depending on the chosen option such as shifting left or shifting up. This is different from the Clear Content command which only removes text numbers or formulas while leaving the cell structure intact. Understanding this difference is essential in spreadsheet programs like Microsoft Excel. Proper use of Edit > Delete helps in managing and organizing data effectively in tables databases and reports.

To calculate the percentage loss we first find the actual loss which is equal to purchase price minus selling price. In this case purchase price is Rs 20000 and selling price is Rs 16000 so the loss is Rs 4000. Next the percentage loss is found by dividing the loss by the purchase price and multiplying by one hundred. That is 4000 divided by 20000 multiplied by 100 which equals 20 percent. This shows the seller faced a significant loss on the deal. Calculating profit or loss percentages is a common concept in business accounting and competitive exams.

A linear equation is called linear because the highest power of the variable is one. For example equations like 2x plus 3 equals 0 or y equals mx plus c are linear equations. If the power of the variable is two the equation becomes quadratic. If it is three it is cubic and if four it is quartic. Linear equations represent straight lines when drawn on a graph. They are widely used in algebra economics physics and engineering to model simple relationships. Therefore the power of a linear equation is always one which makes option A the correct answer.

Work problems are solved using the formula Work equals Men multiplied by Days. If 10 men can finish in 40 days then total work is 10 multiplied by 40 which is 400 man days. Now for one man to do the same work alone it will take 400 days. This is because one man completes only one unit of work per day while 10 men together complete ten units. Such problems show the inverse relationship between number of workers and time. These calculations are practical in construction projects business planning and exams that test arithmetic reasoning.

Adjectives in English have three forms which are positive comparative and superlative. The positive form describes a quality without comparison such as tall. The comparative form is used when comparing two things and often ends in er such as taller. The superlative form describes the highest degree among three or more such as tallest. In this question taller is the correct comparative form because it compares height between two subjects. Words like angry and bad are positive forms while worst is superlative. Comparative degrees are essential in grammar because they allow clear and accurate communication in descriptive language.

The word remember is divided into syllables to understand its structure in phonetics. Syllables are units of pronunciation containing a vowel sound. The correct breakdown for remember is rem ber ed which shows the word has three distinct syllables. Each syllable plays a role in proper pronunciation and stress patterns in English.

The phrase to help is an example of an infinitive verb. An infinitive is formed by using the word to followed by the base form of the verb such as to eat to write or to help. Infinitives can function as nouns adjectives or adverbs within a sentence. They are very flexible and used widely in English grammar. Participles are used to show tense or form adjectives while gerunds are ing forms used as nouns. Modals are auxiliary verbs that show possibility necessity or permission. Therefore to help is correctly classified as an infinitive making option B the right answer.

Rearranging letters of a given word to form another word is called an anagram. In this case the letters of the word South can be rearranged to form the word Those. Anagram based questions test vocabulary recognition spelling and ability to reorganize letters into meaningful words. Such puzzles improve analytical thinking and are common in competitive exams. While other options like South remain unchanged and Thou is a different old word the correct rearranged meaningful option is Those. Word formation plays a key role in understanding English language structure and improving problem solving skills in word related exercises.

In English grammar the modal verb may is often used to express permission. For example May I use your pen is a polite way of asking if the speaker has permission to use the object. Modal verbs like may can express possibility necessity obligation and probability depending on context. In this sentence it is not request direction or choice but clearly permission. Understanding modal verbs is important for both writing and speaking because they add precision to communication. May has a formal tone compared to can which is more casual. Therefore the correct meaning in this sentence is permission.

The correct word to complete the sentence is best. This is because the structure indicates a superlative degree is required to compare one student with all others in the class. Best is the superlative form of good and shows the highest level of quality or achievement. Other words like top prime or lead can describe status but do not fit as grammatical superlatives in this sentence. The use of superlative forms is a key part of English grammar and helps in expressing maximum degree of qualities. Thus the answer best is correct and fits perfectly in this context.

The correct plural of family is families. When a noun ends in y preceded by a consonant the y is changed to ies to form the plural. For example baby becomes babies and city becomes cities. Family follows the same pattern and changes to families in the plural form. This rule helps learners understand standard English spelling practices. Incorrect forms like familys or famlies do not follow this rule and are grammatically wrong. Using correct plural forms is essential for proper writing and speaking. Therefore families is the right answer to this question about English grammar.

The word who is a pronoun in English grammar. It is used as an interrogative pronoun in questions such as Who is coming or as a relative pronoun in sentences such as The person who helped me. Pronouns replace nouns to avoid repetition and make sentences smoother. Who specifically refers to people and plays an important role in both spoken and written English. It cannot be classified as noun adverb or adjective in this context. Correct identification of pronouns helps learners improve their understanding of grammar structure and sentence construction which is tested in many competitive examinations.

The correct adverb of place among the given options is abroad. Adverbs of place describe where an action happens. For example sentences like He went abroad or She looked around demonstrate location of action. Words like vast great and gigantic are adjectives describing quality or size not place. Adverbs of place are very important in communication because they provide clarity about the location or direction of activities. In competitive exams identifying adverbs tests understanding of parts of speech and sentence structure. Thus abroad is the correct option because it shows where the action is taking place.

The correct phrase to complete the sentence is give up. The sentence means that the student continues working hard and does not surrender or quit. Give up is a phrasal verb that expresses the idea of stopping effort or abandoning a task. Stop and refuse do not convey the same meaning in this context. Phrasal verbs are a common part of English language and mastering them is essential for fluency. They often have meanings that cannot be guessed from the words alone. Therefore give up is the best choice and fits the meaning of the given sentence correctly.

The sentence He is working now shows an action that is happening at the present moment. This tense is called present continuous tense. It is formed using the subject plus is or are plus verb with ing form. For example She is reading or They are playing are also present continuous sentences. Present indefinite tense expresses regular actions and present perfect continuous describes actions continuing over a period of time. In this case the presence of is and verb with ing makes it clear that it is present continuous. This tense is important in daily communication and English grammar.

The correct word to complete the sentence is where. The sentence becomes Karachi is the city where Quaid e Azam was born in 1876. The word where is a relative adverb used to refer to place in a sentence. While is used to show time which would not make sense here. Which and whom are relative pronouns but they cannot correctly indicate a place. Understanding the correct use of relative adverbs and pronouns is important for sentence construction. Therefore the right choice is where because it points to Karachi as the location of Quaid e Azam birth.

The sentence The luggage is as light as feather is an example of simile. A simile is a figure of speech where two different things are compared using words such as like or as. In this case luggage is compared to feather to show lightness. A metaphor would directly say The luggage is a feather which is different from simile. Personification gives human qualities to non human things and hyperbole exaggerates an idea. Figures of speech are commonly used in literature poetry and daily language. They add beauty expression and creativity to communication. Thus simile is the correct answer.

The word quell means to suppress or put an end to something often used in the context of stopping protests or controlling anger. Its antonym is agitate which means to stir up excite or provoke. Words like peace calm and under control are synonyms rather than antonyms of quell.
