One mole of a diatomic (rigid rotator) ideal gas has an initial volume of 1 L and temperature of 400 K (state A). First the gas undergoes an isometric process such that the final pressure is 4 times the initial pressure (state B). It then expands isothermally back to the initial pressure (state C). Then it is compressed isobarically back to its original state.

1. Draw a PV diagram illustrating the above cycle. On the diagram indicate where the 3 different processes occur. Create a table of the pressure, volume, temperature, and internal energy values at the 3 points (states A, B and C).

2. How much work is done during the isothermal process?

3. How much heat is added during the isobaric process?

4. What is the net work done for the cycle and what is the efficiency of the engine?

PLEASE show work for all 4 problems I have answers for them.. just want to compare results.. Thank you
