In which of the following conditions, does the thermodynamic system DOES NOT perform any work?
Correct answer: B. Isochoric condition
- A. Adiabatic condition
- B. Isochoric condition
- C. Isobaric condition
- D. Isothermal condition
Explanation
In an isochoric process, the volume remains constant. Since work is defined as W=PΔV, where ΔV=0 means no work is performed. Therefore, no work is done in this process.

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.
