Q.

5 moles of an ideal gas at 100 K are allowed to undergo reversible compression till its temperature becomes 200 K. If CV = 28 J K–1 mol–1, calculate U and pV for this process.

(R = 8.0 J K–1 mol–1)

  1. A

    U = 14 kJ; (pV) = 18 kJ

  2. B

    U = 2.8 kJ; (pV) = 0.8 kJ

  3. C

    U = 14 J; (pV) = 0.8 J

  4. D

    U = 14 kJ; (pV) = 4 kJ
