Question

which gas is used as colling agent​

Answer 1

Answer:

Liquid nitrogen (LIN) and carbon dioxide (CO2) are extremely effective cooling agents due to the low boiling point of LIN (-196°C) and the low sublimation point of CO2 (-78.5°C). Liquid carbon dioxide converts to solid carbon dioxide snow at –79ºC (–109ºF).
