State the basic steps involved in the working of a heat engine.

1.	State the basic steps involved in the working of a heat engine.
Answer» 1. The working substance absorbs heat (Q_H) from a hot reservoir at constant temperature. T_H . It is an isothermal process Q_H is positive. 2. Part of the heat absorbed by the working substance is converted into work (W), i.e. mechanical energy. In this case, there is a change in the volume of the substance. 3. The remaining heat (\|Q_C\| = \|Q_H\| – W) is transferred to a cold reservoir at constant temperature T_C < T_H . Q_C is negative.
