Question

A partition divides a container having insulated walls into two compartments I and II. The same gas fills the two compartments [See Fig]. The ratio of the number of molecules in compartments I and II is

• A. 1:6
• B. 6:1
• C. 4:1
• D. 1:4

Answer 1

The correct option is D

1:4

$n=\frac{PV}{kT}Now,n^{\prime }=\frac{\left(2P\right)\left(2V\right)}{kT}=4n;\frac{n}{n},=\frac{1}{4}$
