When a van der waals ' gas undergoes free expansion , then its temperature

A

Decreases

B

Increases

C

Does not change

D

Depends upon the nature of the gas

Text Solution

Verified by Experts

The correct Answer is:
A
Real gases experience a temperature change during free expansion. For an ideal gas, the temperature does not change for expansion, `v_fgtv_irArr` temperature decreases
