Answer to Question #318259 in Molecular Physics | Thermodynamics for chan

Question

A Carnot heat engine uses a hot reservoir consisting of a

large amount of boiling water and a cold reservoir consisting of a

large tub of ice and water. In 5 minutes of operation, the heat

rejected by the engine melts 0.0400 kg of ice. During this time,

how much work W is performed by the engine?

Answer 1

$W=\lambda m=334\cdot 0.04=13.4~J.$
