List I describes thermodynamic processes in four different systems. List II gives the magnitudes (either exactly or as a close approximation) of possible changes in the internal energy of the system due to the process.

List-I

List-II

(I)

10−3‌kg of water at 100∘C is converted to steam at the same temperature, at a pressure of 105‌Pa. The volume of the system changes from 10−6m3 to 10−3m3 in the process. Latent heat of water =2250‌kJ∕kg.

(P)

2KJ

(II)

0.2 moles of a rigid diatomic ideal gas with volume V at temperature 500K undergoes an isobaric expansion to volume 3V. Assume R=8.0Jmol−1K−1.

(Q)

7KJ

(III)

On mole of a monatomic ideal gas is compressed adiabatically from volume V=‌

m3 and pressure 2‌kPa to volume ‌

(R)

4KJ

(IV)

Three moles of a diatomic ideal gas whose molecules can vibrate, is given 9‌kJ of heat and undergoes isobaric expansion

(S)

5KJ

(T)

3KJ
