The complete conversion of heat into shaft- work is impossible.

Question

Quizplus · Accepted Answer

This statement is true due to the Second Law of Thermodynamics, which states that it is impossible for a process to have as its sole result the transfer of heat from a cooler body to a hotter body or the complete conversion of heat into work without leaving any effect on the surrounding environment. This principle is often illustrated by the Kelvin-Planck statement, indicating that no process is possible whose sole result is the conversion of heat into work.
