A Carnot heat engine uses a steam boiler at 100°C as the high-temperature reservoir. The low-temperature reservoir is the outside environment at 20.0°C. Energy is exhausted to the low-temperature reservoir at the rate of 15.4 W.
(a) Determine the useful power output of the heat engine.
(b) How much steam will it cause to condense in the high temperature reservoir in 1.00 h?
