A cylinder closed at both ends is divided into two compartments by a frictionless and freely moveable piston; both the piston and cylinder are perfectly insulated regarding heat interactions. One compartment contains air and other contains nitrogen. Initially both air and nitrogen are at 1.0 bar pressure 298 K temperature and 0.02 m3 volume. An electric heater on the side of air compartment heats the air till the volume of nitrogen is reduced to 0.01 m3. Evaluate the final temperature of air and heat supplied to it. Take for air Cv = 715 J/kg k, R = 287 J/kg-k and for nitrogen γ = 1.4
