Answer
The correct answer is:
(d) I = isobaric; II = isothermal; III = isochoric
Work Step by Step
In process I, the pressure is constant, so this process is isobaric.
In process II, the temperature is constant, so this process is isothermal.
In process III, the volume is constant, so this process is isochoric.
The correct answer is:
(d) I = isobaric; II = isothermal; III = isochoric
