Question

The plots between P and V which represent isochoric and isobaric process respectively are:

• A. I, II
• B. IV, I
• C. I, IV
• D. II, III

Answer 1

The correct option is B IV, I

The thermodynamic processes which take place at a constant volume are called isochoric processes.
Thus, process IV is isochoric.

The thermodynamic processes which take place at a constant pressure are called isobaric processes.
Thus, process I is isobaric.
