JEE Main 2025 — 29 January, Morning Shift — Question 38

The workdone in an adiabatic change in an ideal gas depends upon only :

  1. Option A:

    change in its pressure

  2. Option B:

    change in its specific heat

  3. Option C:

    change in its volume

  4. Option D:

    change in its temperature

    Correct

Answer: D

Step-by-step solution

ΔW=−ΔU=−nCvΔT\quad \Delta \mathrm{W}=-\Delta \mathrm{U}=-\mathrm{nC}_{\mathrm{v}} \Delta \mathrm{T}
