    In pressure-volume diagram, the isochoric, isothermal, isobaric and iso-entropic parts respectively, are

    A) BA, AD, DC, CB

    B) DC, CB, BA, AD

    C) AB, BC, CD, DA

    D) CD, DA, AB, BC

    Correct Answer: D

    Solution :

    [d] From C to D, V is constant. So process is isochoric. From D to A, the curve represents constant temperature. So the process is isothermal. From A to B, pressure is constant. So, the process is isobaric. BC represents constant entropy.
