Thermo Hw question I got a quick question about a problem from my thermodynamics homework sheet. I broke my leg badly last week and I haven't been in class, and the homework is due at midnight online, and the notes/book don't do much to help unfortunately. Any help at all would be greatly appreciated. "At state A: U = 1.0 kJ, P = 10.0 bar, V = 1.0 L At state B: U = 5.0 kJ, P = 10.0 bar, V = 5.0 L At state C: U = 0.2 kJ, P = 2.0 bar, V = 1.0 L IMPORTANT: Provide your answer to the nearest hundredth of a digit. The cycle runs as a heat cycle. What is the coefficient of performance?"
