Consider a heat engine that operates on a Carnot cycle and uses an ideal gas as a working fluid. Suppose that the heat reservoir of the engine supplies 1 kJ of heat to the system during an isothermal expansion process at a temperature of 900 K, and the system subsequently gives up heat to heat sink during an isothermal compression process at a temperature of 300 K. What would be the maximum efficiency (ηmax) achievable with this engine, and what would be the maximum net work (wnet,max) that one could derive from this engine?
