  List-I   List-II
  Thermodynamic Process   Magnitude in kJ
A. Work done in reversible, isothermal expansion of 2 mol of ideal gas from 2 dm3 to 20 dm3 at 300 K. I. 4
B. Work done in irreversible isothermal expansion of 1 mol ideal gas from 1 m3 to 3 m3 at 300 K against a constant pressure of 3 kPa. II. 11.5
C. Change in internal energy for adiabatic expansion of a 1 mol ideal gas with change of temperature = 320 K and C¯V=32R. III. 6
D. Change in enthalpy at constant pressure of 1 mol ideal gas with change of temperature = 337 K and C¯P=52R. IV. 7
