A gas no longer acts ideally when A intermolecular attracati

A gas no longer acts \'ideally\' when

A) intermolecular attracative forces are small

B) volumes of molecules are very small

C) gas is under high pressure

D) gas is under very low pressure

Solution

B ) when volumes of molecules are very small because then their mean free path decreases and they more often collide with each other and deviate from the ideal nature.

In all other option the gas behaves ideally.
