Question

Why cooling is produced when a gas at high pressure suddenly expands?​

Answer 1

Cooling is produced when a gas at high pressure suddenly eexpands because due go high pressure molecules expands. Therefore, when you heat air it expands to allow more space for the molecules. and cools itself.

Molcules expand and cooling is producex to again gain the same size by contraction. If high pressure is given, due to know due to cooling contraction occurs

Answer 2

Answer:

Due to decrease in internal energy.

Explanation:

During its expansion, the gas does work against high pressure. This decreases the internal energy and hence the temperature of the gas.

Hope this helps.
