A thermal cycle has an efficiency equal to 45.0 % of that a Carnot engine that operates between the temperature extremes of the thermal cycle, a low of -70.0 degrees C and a high of 60.0 degrees C. If 9,000.0 J of energy flow into the system at the high temperature in one cycle, how much work is done in the cycle?

Heat of amount 250 J is removed from a heat reservoir at a temperature of 270 K. What is the entropy change of the reservoir? Hint   ΔS=ΔS= J/KJ/K. (Use the sign to indicate whether entropy of reservoir increases or decreases.) Submit QuestionQuestion 9 It is found that an engine discharges 50 J while absorbing 85 J each cycle of operation. Hint   What is the efficiency of the engine? eff=eff= How much work does it perform per cycle? W=W= J

Refrigeration Cycle Operating As Shown In The Figure Below Has A Coefficient Of Performance Β = 1.8. For The Cycle, Qout = 250 kj. Determine Qin and Wcycle, each in kJ
