Two mole of an ideal diatomic gas initially at pressure 5*10^5 pa and volume 0.0

Question

Two mole of an ideal diatomic gas initially at pressure 5*10^5 pa and volume 0.028m^3 is first heated isothermally until the volume doubles. Then the gas is allowed to expand adiabatically until the volume becomes three times the initial value. The gas is then compressed at constant volume until it reaches the original volume of 0.028m^3 and then is heated at constant volume until it reaches the initial pressure of 5*10^5.
