Which of the following statements about intermolecular distances and cohesive forces between gas is correct? They are

A.

Both large

B.

Both negligible

C.

Constant and negligible

D.

Large and negligible

Correct answer is D

In a gas, the distance between molecules, whether monatomic or polyatomic, is very large compared with the size of the molecules; thus gases have a low density and are highly compressible.

Cohesive Force is negligible in case of gases.
