Class 11 NEET Physics Thermodynamics and Kinetic Theory

A container has two chambers of volumes V1=2 litres and V2=3 litres separated by a partition made of a thermal insulator. The chambers contain n1=5 and n2=4 moles of ideal gas at pressures p1=1‌atm and p2=2‌atm, respectively. When the partition is removed, the mixture attains an equilibrium pressure of
