Correct answer: B. Isochronic
- A. Isothermal
- B. Isochronic
- C. Adiabatic
- D. Isobaric
Explanation
Isochronic or isochoric processes are carried out at constant volume.

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.
