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