A 10 liter container consist of 1 mole of gas at 300 K. It is connected to another container having volume 40 liter and is initially at 300 K. The nozzle connecting two containers is opened for a long time and once the movement of gas stopped, the larger container was heated to a temperature of 600 K. Calculate

(A) Moles and pressure of gas in both the containers before heating. (B) Moles and pressure in two containers after heating. Assume that initially the larger container is completely evacuated.
