Work done in an adiabatic process in a gas depends on _.
Correct answer: B. Change in temperature
- A. Change in pressure
- B. Change in temperature
- C. Change in volume
- D. All of these options are correct
Explanation
Since no thermal energy is taken in or given out in an adiabatic process, ΔQ = 0. Hence using 1st Law of Thermodynamics, the equation becomes ΔU = W. Therefore, work done only depends on the change in the internal energy, which depends on the change in KE of the molecules, which depends on the change in thermodynamic temperature. Hence Option B is correct.

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.
