If the volume of a gas is doubled either...

If the volume of a gas is doubled either isothermally or adiabatically, in which case change in mean free path is more.

A

Adiabatic

B

Isothermal

C

Same in both

D

No change

Text Solution

Verified by Experts

The correct Answer is:
D
We know that mean free path is the effective average distance which molecules does not collide with other molecules and it is given
`lambda=(v)/(sqrt(2)pi d^(2)n)`
[`d to` diameter of molecule, `n to` number of molecule, `v to` volume of gas]
So `lambda` depends on ` v rArr ` Change in `lambda` will be same in both case.
