With increase in pressure, the mean free path

A

Decreases

B

Increases

C

Does not change

D

Becomes zero

Text Solution

Verified by Experts

The correct Answer is:
A

On increasing pressure, the volume decreases and density increases. So molecules get closer to each other hence mean free path also decreases.
