0.5 mole of an ideal gas starts from point a in the diagram to the right. It undergoes a constant 500 a b 400 pressure expansion from a to b; a constant volume compression from b to c: and an isothermal 300 compression from c to a. 200 Find the three temperature values Ta, Tb and Tc. Find values for the work done along the three 100 processes Wab, Wbc and Wca and the total work for one cycle W. 1 2 3 4 volume (m³) pressure (Pa)
