If the mean free path is ' lambda' at on...

If the mean free path is ' `lambda`' at one atm pressure then its value at 5 atm pressure is

A

`5 lambda`

B

`2/5 lambda`

C

`lambda/5`

D

unpredictable.

Text Solution

Verified by Experts

The correct Answer is:
C
`lambda alpha 1/(P) implies (lambda_1)/(lambda_2) = (P_2)/(P_1) implies (lambda_b)/(lambda_L) = 5/1 implies lambda_2 = lambda/5`.
