Question

what is heat engine...​

Answer 1

Answer:

In thermodynamics and engineering, a heat engine is a system that converts heat or thermal energy—and chemical energy—to mechanical energy, which can then be used to do mechanical work. It does this by bringing a working substance from a higher state temperature to a lower state temperature.

HEAT ENGINE WORKING-

The gas takes energy from a heat source, expands, cools, and pushes a piston out. As the piston returns into the cylinder, it compresses and heats the gas, so the gas ends the cycle at exactly the same pressure, volume, and temperature it started off with. REFER TO THE ATTACHMENT...
