One mole of gas is taken through a four step process in a closed system. Consider the following steps:
1 ? 2: The gas goes through an isothermal expansion at 600 K from 5 to 4 bar
2 ? 3: The gas goes through an adiabatic expansion from 4 bar to 3 bar
3 ? 4: The gas goes through an isobaric cooling at 3 bar
4 ? 1: The gas goes through an isochoric heating to 600 K.
If you assume the gas behaves ideally with CP=(7/2)R, please determine Q, W, ?H and ?U for each step. (Hint: Calculate T, P and v for each state point)
