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

Answer:

                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.
