3) Consider a well-insulated piston-cylinder assembly. It is well-insulated and on the 0.04 m² piston rests two 3000-kg blocks. The initial temperature is 600 K. The ambient pressure is 4 bar. One mole of an ideal gas is contained in the cylinder. The gas is compressed in a process in which another 3000-kg block is added. The heat capacity at constant volume can be taken to have a constant value of (5/2)R.

A piston/cylinder setup contains 1 kg of air at 20°C with an initial volume of V1=0.1 m3, as shown in Fig. Q7. Initially, the piston rests on some stops, but it is possible for it to move within the cylinder without friction. To lift the piston and start such motion, an air pressure of 1400 kPa is required. Now, heat is transferred to the system so that the temperature of the air reaches to a final value of 300°C. Fig. Q7 A. Which statement is true?
