For each of the cases below, determine if the system is a heat engine or refrigerator (please look at the signs of Q7, W and Q,). Then, determine if each case satisfies the first law (energy balance) and if it violates the second law of Thermodynamics. QH = 10 kW QH = -8 kW QH = -6 kW QH = 7 kW ģ, = -4 kW QL = 8 kW ģ, = 5 kW Q, = -2 kW W = 6 kW W = 0 kW W = -1 kW W = 8 kW а. b. c. d.
