Serway & Jewett — Heat Engines, Entropy, and the Second Law of Thermodynamics: Problem 3
Suppose a heat engine is connected to two energy reservoirs, one a pool of molten aluminum (660°C) and the other a block of solid mercury (238.9°C). The engine runs by freezing 1.00 g of aluminum and melting 15.0 g of mercury during each cycle. The heat of fusion of aluminum is 3.97 3 105 J/kg; the heat of fusion of mercury is 1.18 3 104 J/kg. What is the efficiency of this engine?
📝 Solution Approach
Given: 660°C, 238.9°C, 1.00 g, 15.0 g, 105 J, 104 J
