Reference no: EM131182392

Suppose that a heat engine is connected to two energy reservoirs, one a pool of molten aluminum (660degrees Celsius) avid the other a block of solid Mercury (-38.9 degrees cel just). The engine runs by freezing 1g of aluminum And melting 15 g of mercury during each cycle. The heat of fusion of aluminum is 3.97*10^5J/kg. The heat of fusion of mercury is 1.18 *10^4J/kg.

What is the efficiency of this engine?

What is the maximum possible efficiency of this engine?
