Dr jeeves has invented a new kind of heat engine that

1. Consider a freezer that is being used to produce 20.0 g of ice each minute. What power is required if the ice is at -15 degrees celcius and the water is at 18 degrees celcius? Assume the refrigerator has a coefficient of performance of 2.50.

2. Dr Jeeves has invented a new kind of heat engine that operates using a pool of molten copper at 1083 degrees celcius and a block of solid lead at 327 degrees celcius. The engine runs by freezing 10.00 g of copper and melting 25.0 g of lead each minute.

(a) What is the efficiency of this engine?

(b) How much power is produced by the engine?
