One can compare one’s body with that of a
heat engine. Since like a heat engine, the human
body also undergoes a cyclic process every day. To
recall, a heat engine needs a source of energy (heat
or Q) and it performs useful work (W). Suppose you
are comparing John’s body with a heat engine. In
your understanding, where does John’s body get its
heat (Q) and what are the ways can it perform work
(W)? Explain in 3-5 sentences.
