Answer 1

Answer:

We know that a heat engine is used to produce mechanical energy by using heat energy as a source. To be precise, it uses fuel such as petrol or diesel and converts its chemical energy into thermal energy by burning it. This thermal energy is then used to move mechanical parts, thus producing mechanical energy.
