A refrigeration cycle is composed of the following steps. The refrigerant is a monoatomic ideal gas (Cp=2.5R,Cv=1.5R) having temperature independent heat capacities. 1. Irreversible compression from state 1 to state 2 (compressor efficiency of 0.9) 2. Reversible isothermal cooling from state 2 to state 3. 3. Reversible adiabatic expansion in a turbine from state 3 to state 4 . 4. Reversible isothermal heating from state 4 to state 1. (a) The table below lists the temperature, pressure, specific volume, and entropy of the ideal gas at each point of the cycle. Please fill in the missing values. (b) Calculate the coefficient of performance of this refrigerator
