If the pressure in a closed vessel is reduced by drawing out some gas, the mean free path of the molecules

Question

If the pressure in a closed vessel is reduced by drawing out some gas, the mean free path of the molecules (A) is decreased (B) is increased (C) remains unchanged (D) increases of decreases according to the nature of gas

Tardigrade Admin · Accepted Answer

The distance travelled by a molecule between two consecutive collision is called mean free path. If pressure is reduced, r molecule will travel longer distance before collision, so mean free path is increased.
