Refer to the thermodynamics cycle represented in figure 1. One mole of a monatomic ideal gas at a temperature Ta = 1200 K and pressure pa = 600 kPa. The gas is allowed to expand at constant pressure until the volume has increased by a factor of 3. The gas is then taken through an isochoric process until the pressure is halfed; the gas is thereafter compressed to its initial volume and finally it is restored to its initial state isochorically. a) Find the work done by the system and the heat exchanged in each of the four

Refer to the thermodynamics cycle represented in figure 1. One mole of a monatomic ideal gas at a temperature Ta = 1200 K and pressure pa = 600 kPa. The %3D gas is allowed to expand at constant pressure until the volume has increased by a factor of 3. The gas is then taken through an isochoric process until the pressure is halfed; the gas is thereafter compressed to its initial volume and finally it is restored to its initial state isochorically. a) Find the work done by the system and the heat exchanged in each of the four processes. b) Calculate the efficiency of this engine.
