An Ideal Carnot Engine Operates Between Reservoirs Having Temperatures of 125°C

question 24

Short Answer

An ideal Carnot engine operates between reservoirs having temperatures of 125°C and
-20°C.Each cycle the heat expelled by this engine is used to melt 30.0 g of ice at 0.00°C.The heat of fusion of water is 3.34 × 10⁵ J/kg and the heat of vaporization of water is
2.25 × 10⁶ J/kg.
(a)How much work does this engine do each cycle?
(b)How much heat per cycle does this engine absorb at the hot reservoir?
