Two kg of air is contained in a piston-cylinder assembly. The initial volume is 0.01m^3 and pressure is 10 bar. the air is expanded to a final pressure of 10 bar and volume 0.02m^3. Fifty five kJ of heat is transferred to the air during this process. Determine the change in specific internal energy of the air. The pressure is constant during the process.
