Following conditions must be fulfilled to utilize heat for a useful work:

(i)  A device called engine with a working substance is essential.

(ii)  The engine must work in a reversible cyclic process.

(iii)  The engine must operate between two temperatures.  It will absorb heat from a hot body ( called the source), convert a part of it into useful work and reject the rest to a cold body (called the sink).
