some examples

An inventor claims to have devised a cyclic engine which exchanges heat with reservoirs at 27°C and 327°C, and which produces 0.6 kJ of work for each kJ of heat extracted from the hot reservoir. Is the claim believable? If instead he claimed that the delivered work would be 0.25kJ / kJ of extracted heat, would the engine be feasible?An inventor claims to have devised a cyclic engine which exchanges heat with reservoirs at 27°C and 327°C, and which produces 0.6 kJ of work for each kJ of heat extracted from the hot reservoir.
