Please solve the question in the picture 

Four moles of a diatomic ideal gas are taken through a three-process thermodynamic cycle.
The gas initially has a pressure of 6.00 atm with a volume of 8.00 L (point A). The gas it then expanded
adiabatically to point B where the temperature of the gas is 100 K. The pressure of the gas is then
increased via an isochoric process (point C). The gas is then compressed .isothermally back to its initial
state. For all calculations using the ideal gas law assume that R = 0.08
For any calculations of
work, heat, internal energy, or entropy use R = 8.0
