A van der waals gas may behave ideally when-

A

volume is very low

B

temperature is very high

C

the pressure is very low

D

the temperature, pressure and volume all are very high.

Text Solution

Verified by Experts

The correct Answer is:
B, C
A van der waals gas behaves ideally when its temperature is very high or pressure is very low. At either of these two conditions, volume of the gas becomes very large, which results in large separation of gas molecules. Thus, intermolecular forces of attraction become negligible, and gas behaves approximately like an ideal gas.
