3. an engine’s fuel is heated to 2,000 k and the surrounding air is 300 k. calculate the ideal efficiency of the engine. hint: the efficiency (e) of a carnot engine is defined as the ratio of the work (w) done by the engine to the input heat qh : e=w/qh. w=qh – qc, where qc is the output heat. that is, e=1-qc/qh =1-tc/th, where tc for a temperature of the cold reservoir and th for a temperature of the hot reservoir. the unit of temperature must be in kelvin.
