Two identical containers each of volume 
are joined by a small pipe. The containers contain identical gases at temperature 
and pressure 
. One container is heated to temperature 
while maintaining the other at the same temperature. The common pressure of the gas is P and n is the number of moles of gas in container at temperature

(b, c)
Initially for container A 
For container B 
∴ ∴ 
Total number of moles 
Since even on heating the total number of moles is conserved
Hence 
......(i)
If P be the common pressure then
For container A 
∴ ∴ 
For container B 
∴ ∴ 
Substituting the value of 
and 
in equation (i) we get 
⇒ ⇒ 
No. of moles in container A (at temperature 
)
=
