In a thermodynamic process on an ideal monatomic gas, the infinitesimal heat absorbed by the gas is given by T$$\Delta$$X where T is temperature of the system and $$\Delta$$X is the infinitesimal change in a thermodynamic quantity X of the system. For a mole of monatomic ideal gas, $$X = {3 \over 2}R\,\ln \left( {{T \over {{T_A}}}} \right) + R\,\ln \left( {{V \over {{V_A}}}} \right)$$

Here, R is gas constant, V is volume of gas, TA and VA are constants.

The List-I below gives some quantities involved in a process and List-II gives some possible values of these quantities.

If the process on one mole of monatomic ideal gas is as shown in the TV-diagram with $${P_0}{V_0} = {1 \over 3}R{T_0}$$, the correct match is,

A
I $$\to$$ P, II $$\to$$ R, III $$\to$$ T, IV $$\to$$ S
B
I $$\to$$ P, II $$\to$$ T, III $$\to$$ Q, IV $$\to$$ T
C
I $$\to$$ S, II $$\to$$ T, III $$\to$$ Q, IV $$\to$$ U
D
I $$\to$$ P, II $$\to$$ R, III $$\to$$ T, IV $$\to$$ P
