Answer Q.17 and Q.18 by appropriately matching the lists based on the information given in the paragraph. In a thermodynamic process on an ideal monatomic gas, the infinitesimal heat absorbed by the gas is given by TΔX, where T is temperature of the system and ΔX is the infinitesimal change in a thermodynamic quantity X of the system. For a mole of monatomic ideal gas X = (3/2)R ln(T/T_A) + R ln(V/V_A). Here, R is gas constant, V is volume of gas, T_A and V_A are constants. List-I: (I) Work done by the system in process 1→2→3, (II) Change in internal energy in process 1→2→3, (III) Heat absorbed by the system in process 1→2→3, (IV) Heat absorbed by the system in process 1→2. List-II: (P) (1/3)RT₀ ln 2, (Q) (1/3)RT₀, (R) RT₀, (S) (4/3)RT₀, (T) (1/3)RT₀(3 + ln 2), (U) (5/6)RT₀.
If the process carried out on one mole of monatomic ideal gas is as shown in figure in the PV-diagram with P₀V₀ = (1/3)RT₀, the correct match is,
