If this cycle were reversed, would it be a engine or a refrigerator? What was the efficiency (or coefficient of performance) of this reversed cycle? Is it possible to have an engine do work without an exhaust, i.e. direct conversion of heat to work, 100% efficiency? Why or why not?Tutorial 13 Page 3 of 4 Complete the bar charts below for the transition from C to A Ui + Q - W = Uf Temp P V I F F IF For transition from C to A: Quantitatively, how much work does the gas do or is done on the gas? How much heat flows in or is exhausted? What type of process is C to A? 1) During which process(es) is heat put into the gas? 2) During which process(es) is heat extracted or exhausted from the gas? 3) How much work did the Gas do? 4) How much work is done on the gas? Efficiency of an engine is defined as the total of all work done by the gas and on the gas divided by the amount of heat to the engine. The coefficient of performance of a refrigerator is defined as the amount of heat extracted by the gas divided by the amount of work done ON the gas. The coefficient of performance of a heat-pump is defined as the amount of heat exhausted by the gas divided by the amount of work done on the gas. Is this cycle an engine or a refrigerator
