JEE Main 2024 — 5 April, Shift 1 — Question 46

The heat absorbed by a system in going through the given cyclic process is :

Question figure
  1. Option A:

    61.6 J

    Correct
  2. Option B:

    431.2 J

  3. Option C:

    616 J

  4. Option D:

    19.6 J

Answer: A

Step-by-step solution

ΔU=0\Delta \mathrm{U}=0 (Cyclic process)

ΔQ=W=\Delta \mathrm{Q}=\mathrm{W}= area of P−V\mathrm{P}-\mathrm{V} curve.

=π×(140×103 Pa)×(140×10−6 m3)=\pi \times\left(140 \times 10^{3} \mathrm{~Pa}\right) \times\left(140 \times 10^{-6} \mathrm{~m}^{3}\right)

ΔQ=61.6 J\Delta \mathrm{Q}=61.6 \mathrm{~J}
