10. In pressure-volume diagram given below, the isochoric, isothermal, and isobaric parts respectively, are
(a) BA, AD, DC
(b) DC, CB, BA
(c) AB, BC, CD
(d) CD, DA, AB
Explanation-(d) Process CD is isochoric as volume is constant, Process DA is isothermal as temperature constant and Process AB is isobaric as pressure is constant.
