Work done in an adiabatic process depends upon:
Correct answer: B. Change in temperature
- A. Change in pressure
- B. Change in temperature
- C. Change in volume
- D. All of these are correct
Explanation
In an adiabatic process, there is no heat exchange (Q=0), so first law of thermodynamics becomes ΔU = -W. For ideal gas, the change in internal energy (ΔU) depends only on change in temperature (ΔT). Therefore, the work done in an adiabatic process also depends on the change in temperature.

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.
