In an isochoric process, the work done is zero because:
Correct answer: B. Volume is constant
- A. Pressure is constant
- B. Volume is constant
- C. Temperature is constant
- D. Entropy is constant
Explanation
In isochoric process, volume is constant (ΔV = 0), work done (W=PΔV) is zero, regardless change in pressure or temp.

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.
