Acarnot 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 of the engine, the heat rejected by the engine melts a mass of ice equal to 3.45×10−2 kg . throughout this problem use lf=3.34×105j/kg for the heat of fusion for water.
