An ideal gas, initially at 25°C and 1 bar, undergoes the following cyclic processes in a closed system.The cycle is irreversible, and each step has an efficiency of 80% compared with the corresponding mechanically reversible process. The cycle still consists of an adiabatic compression step, an isobaric cooling step, and an isothermal expansion. Calculate Q, W, AU, and AH for each step of the process and for the cycle. Take Cp = (7/2)R and Cy = (5/2)R.
