An engine works with two reservoirs: Ta at 400 degrees Celsius and the other Tb at 200 degrees Celsius. It goes through processes with first adiabatic compression absorbing 150 J then isothermal expansion on Ta then adiabatic expansion then isothermal compression on Tb. Output of the engine operates between the same two reservoirs, with adiabatic expansion, then isothermal expansion at Tbthen adiabatic compression then isothermal compression at Ta. Output of engine runs refrigerator. What is the coefficient of performance of refrigerator and what is the total change in entropy in running the system?
