The work done in the isochoric process is________________?
Correct answer: C. zero
- A. constant
- B. variable
- C. zero
- D. depends on situation
Explanation
In an isochoric process, volume remains constant, so the work W = integral of P dV is zero because dV = 0. The likely mistake is choosing constant, confusing constant volume with a nonzero constant amount of work.

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.
