What cooling agent has a lower temperature than solid water?
What cooling agent has a lower temperature than solid water?
A: Carbon dioxide
B: Ammonia
C: Nitrogen
D: None of these
Carbon dioxide in solid form (dry ice) has a lower temperature than ice reaching -78.5°C. This question tests knowledge of cryogenics in Everyday Science exams. Dry ice is used for cooling in transport and preservation. Its sublimation property makes it effective for specialized applications unlike water ice.
