Question

In figure (a), (b) and (c) given below, identify the isothermal and adiabatic process in each diagram.

Answer 1

For the same values of pressure and volume, the slope of an adiabatic curve is greater than the slope of an isothermal curve.

Using this fact, we find.

(a) 1-isothermal; 2-adiabatic.

(b) 1-adiabatic; 2-isothermal.

(c) 1, 3-isothermal; 2, 4-adiabatic.
