Question

The process which occurs in going from $B\to C$ is :

• A. isothermal
• B. adiabatic
• C. isobaric
• D. isochoric

Answer 1

Answer: (C)

isobaric

Isobaric process is a thermodynamic process in which the pressure stays constant: ΔP = 0.

As in process $B\to C$, the graph $V-T$ is a straight line, i.e., pressure during the process is constant. Hence the process is isobaric.

Therefore, the correct option is C.
