Which cooling agent gas has a lower temperature than solid ice:
Answer: Liquid nitrogen

Liquid nitrogen, with a boiling point of -195.8°C, is colder than solid ice (0°C), used in cryogenics and cooling. Studying this highlights its role in scientific applications, the challenges of handling extreme temperatures, and its impact on industries like medicine and food preservation. It also offers insights into how cryogenics advance technology, providing lessons on leveraging low-temperature agents for innovation in scientific and industrial fields.
