Correct Answer - Option 1 : Zero
The correct answer is option 1) i.e. Zero
CONCEPT:
-
Work done by a thermodynamic system:
- The heat energy supplied to a thermodynamic system increases its internal energy and the remaining heat energy is converted into the work done by the system.
- This work done is due to the heat that can either expand or compress a thermodynamic system.
- Expansion or compression happens with a pressure that causes a change in the volume of the system.
Therefore, work done = ∫P × dV
-
Isochoric process: It is a thermodynamic process where the volume of the system undergoes no change i.e. remains constant.
EXPLANATION:
We know that work done = ∫P × dV
In an isochoric process, the volume remains constant i.e. change in volume (dV) is zero.
Hence, work done in an isochoric process = ∫P × 0 = 0
