Question

Are heat engines reversible?

Answer 1

Explanation:

1. The engine, in which the process can be retraced at any stage of its operation by reversing the boundary conditions, is called a reversible heat engine.
2. Yes, heat engines can be reversible.
3. Its efficiency is maximum, as no dissipation of energy takes place against friction, etc. in such a heat engine.
4. The efficiency of the reversible heat engine is more than an irreversible heat engine that works between the same two thermal reservoirs.
5. The amount of heat energy converted to work is more in a reversible process than in an irreversible process.
