When `H_2` gas is allowed to expand from a region of high pressure to a region of low pressure, the temperature of the gas

A

decreases to a small extent

B

increases

C

does not change

D

decreases suddenly

Text Solution

Verified by Experts

The correct Answer is:
B
When hydrogen, or helium gas is allowed to expand from a region of high pressure to a region of low pressure, the temperature of the gas increases to a small extent. In case of other gases the temperature decreases.
