The thermodynamic process during which volume of the system remains constant is:
Correct answer: C. Isochoric
- A. Isothermal
- B. Isobaric
- C. Isochoric
- D. Adiabatic
Explanation
The correct answer is Isochoric because in an isochoric process, the volume of the system remains constant, meaning no work is done by or on the system. In contrast, an Isothermal process maintains constant temperature, an Isobaric process maintains constant pressure, and an Adiabatic process involves no heat exchange with the surroundings.

About First Law of Thermodynamics
The first law relates heat supplied, work done and the change in internal energy through energy conservation. Problems use sign conventions and apply the law to isothermal, adiabatic, isobaric and isochoric processes. Internal energy is a state function, while heat and work depend on the path followed.
