Question

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

Answer 1

The correct option is D CD, DA, AB, BC

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
