In a Carnot cycle the area for each transformation corresponds to the following work: (a) isothermal expansion: 31,165 J, (b) adiabatic expansion: 21,517 J, (c) isothermal compression: 24,282 J, (d) adiabatic compression: 21,517 J. Calculate (1) the heat provided, per cycle, to the warm source, and (2) the efficiency of the cycle.
