Sol: It is impossible to construct this type of H.E. that operates on cyclic process and converts all the heat supplied to it into equivalent amount of work. The conclusions stated below can be made from statement

1. No cyclic engine can converts whole heat into equivalent work.

2. There is degradation of energy in a cyclic heat engine as some of the heat has to be degraded or rejected.

Therefore second law of thermodynamics is called as law of degradation of energy. For satisfactory operation of heat engine there should be least 2 heat reservoirs source and sink.
