What do you mean by perpetual motion machine of the second kind?

Text Solution

Verified by Experts

A machine working in a cyclic process absrobs heat from a single thermal reservoir and completely converts the heat into equivalent amount of work, is called a perpetual motion machine of second kind. This type of machine contradicts the second law of thermodynamics, & it is impossible to construct.
