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.

(I) | 10–3 kg of water at 100∘C is converted to steam at the same temperature, at a pressure of 105 Pa. The volume of the system changes from 10–6 to 10–3 in the process. Latent heat of water =2250 kJ/kg. | (P) | 2 kJ |
(II) | 0.2 moles of a rigid diatomic ideal gas with volume V at temperature 500 K undergoes an isobaric expansion to volume 3V. Assume R=8.0 J mol−1K−1. |
(Q) | 7 kJ |
(III) | One mole of a monoatomic ideal gas is compressed adiabatically from volume V=13 m3 and pressure 2 kPa to volume V8 | (R) | 4 kJ |
(IV) | Three moles of a diatomic ideal gas whose molecules can vibrate, is given 9 kJ of heat and undergoes isobaric expansion. | (S) | 5 kJ |
(T) | 3 kJ |
