Chapter 24, Problem 14A

What three processes occur in every heat engine?

To determine

Threeprocesses that occur in every heat engine.

Explanation of Solution

Introduction:

As per second law of thermodynamics, the heat transfersfroma body at high temperature spontaneously to a body at lower temperature.Any device that transforms internal energy to mechanical work is called a heat engine.

Three processes that occur in every heat engine are:

1. The internal energy increases by absorbing energy from hot reservoir.
2. Some of the energy is converted into work.
3. The remaining energy is expelled as heat to cold reservoir.
