A cyclical thermodynamic process for 1 mole of a confined ideal gas is shown in the figure. The pressure P, = 250 kPa, the pressure Pac=81.2 kPa. The volume V, = .067 m³ and the volume Vab.03 m³. The process along the path from point b to c is adiabatic. The path from a to b is constant volume. The path from c to a is constant pressure. (a) Find the temperatures at the three points a, b and c. (b) The net amount of work done by this process (for a complete cycle) is 2150 J. How much work is done by the gas during the adiabatic expansion from point b to c? (c) What is the net amount of heat flowing into the gas for a complete cycle? 2 pressure Pa adiabatic volume
