Two containers C₁ and C₂ of volumes V and 4 V respectively hold the same ideal gas and are connected by a thin horizontal tube of negligible volume with a valve which is initially closed. The initial temperature and pressure of the gas in C₁ are 300 K and P , respectively and those in C₂ are 400 K and 5 P , respectively. Heaters are employed to maintain the temperatures in both the containers at their initial values
