JEE Main 2025 — 7 April, Morning Shift — Question 63

Match the LIST-I with LIST-II Choose the correct answer from the options given below:

LIST-ILIST-II
A.Triatomic rigid gasI.CpCV=53\frac{{{C}_{p}}}{{{C}_{V}}}=\frac{5}{3}
B.Diatomic non-rigid gasII.CpCV=75\frac{{{C}_{p}}}{{{C}_{V}}}=\frac{7}{5}
C.Monoatomic gasIII.CpCv=43\frac{{{C}_{p}}}{{{C}_{v}}}=\frac{4}{3}
D.Diatomic rigid gasIV.CpCv=97\frac{{{C}_{p}}}{{{C}_{v}}}=\frac{9}{7}
  1. Option A:

    A-II, B-IV, C-I, D-III

  2. Option B:

    A-III, B-II, C-IV, D-I

  3. Option C:

    A-III, B-IV, C-I, D-II

    Correct
  4. Option D:

    A-IV, B-II, C-III, D-I

Answer: C

Step-by-step solution

For triatomic rigid gas CpCv=43\frac{C_{p}}{C_{v}}=\frac{4}{3}

For diatomic non rigid gas CpCv=97\frac{C_{p}}{C_{v}}=\frac{9}{7}

For monoatomic gas CpCv=53\frac{C_{p}}{C_{v}}=\frac{5}{3}

For diatomic rigid gas CpCv=75\frac{C_{p}}{C_{v}}=\frac{7}{5}
