Homework Statement
1. Consider ideal gas in a rigid cylinder of 2 litres, at pressure of 3 Bar. The gas is connected through a thin capillary to a free expanding bag, which contains ideal gas at pressure 1Bar and volume of 1 litre. A valve in the capillary initially prevents the gases to mix. If the valve is open, calculate the volume of the bag, in thermal equilibrium with the environment. The surrounding atmosphere is at a pressure of 1Bar and temperature T. Neglect the volume of the capillary and valve, as well as the mass and elasticity of the bag. The heat capacity of the surrounding atmosphere is much larger than the heat capacity of the gas in the cylinder and bag. Note: in solving this problem, use the fact that the number of atoms of the gas in the bag and cylinder does not change after opening the valve, i.e. N1+N2 = N1’ +N2’ .Every step of the solution should be clearly given.

The Attempt at a Solution
I haven't really attempted as I don't know where to start as the lack of temperature given deters me.
Could someone please give me a push in the right direction?
Thanks
