Molecular attraction and size of the mol...

Molecular attraction and size of the molecules in a gas are not negligible at

A

Critical point

B

High pressure

C

High temperature and low pressure

D

Low temperature and high pressure

Text Solution

Verified by Experts

Hint: At critical point, the gases can be liquefied and hence there is force of attraction.
At high pressure and low temperature, gases are close to each other and hence they experience force of attraction.
