    One mole of an ideal gas expands adiabatically from an initial state $\left(T_A, V_0\right)$ to final state $\left(T_f, 5 V_0\right)$. Another mole of the same gas expands isothermally from a different initial state ( $T_{\mathrm{B}}, \mathrm{V}_0$ ) to the same final state $\left(T_{\mathrm{f}}, 5 V_0\right)$. The ratio of the specific heats at constant pressure and constant volume of this ideal gas is $\gamma$. What is the ratio $T_{\mathrm{A}} / T_{\mathrm{B}}$ ?

    Answer the following by appropriately matching the lists based on the information given in the paragraph.

    In a thermodynamics 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

    $X=\frac{3}{2} R \ln \left(\frac{T}{T_A}\right)+R \ln \left(\frac{V}{V_A}\right)$. Here, $R$ is gas constant, $V$ is volume of gas, $T_A$ and $V_A$ are constants.

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

    List-$I$ List-$II$
    $(I)$ Work done by the system in process $1 \rightarrow 2 \rightarrow 3$ $(P)$ $\frac{1}{3} R T_0 \ln 2$
    $(II)$ Change in internal energy in process $1 \rightarrow 2 \rightarrow 3$ $(Q)$ $\frac{1}{3} RT _0$
    $(III)$ Heat absorbed by the system in process $1 \rightarrow 2 \rightarrow 3$ $(R)$ $R T _0$
    $(IV)$ Heat absorbed by the system in process $1 \rightarrow 2$ $(S)$ $\frac{4}{3} RT _0$
      $(T)$ $\frac{1}{3} RT _0(3+\ln 2)$
      $(U)$ $\frac{5}{6} RT _0$

    If the process carried out on one mole of monatomic ideal gas is as shown in figure in the PV-diagram with $P _0 V _0=\frac{1}{3} RT _0$, the correct match is,

    $(1)$$I \rightarrow Q, II \rightarrow R , III \rightarrow P , IV \rightarrow U$

    $(2)$ $I \rightarrow S , II \rightarrow R , III \rightarrow Q , IV \rightarrow T$

    $(3)$ $I \rightarrow Q , II \rightarrow R , III \rightarrow S , IV \rightarrow U$

    $(4)$ $I \rightarrow Q , II \rightarrow S , III \rightarrow R , IV \rightarrow U$

    ($2$) If the process on one mole of monatomic ideal gas is an shown is as shown in the $TV$-diagram with $P _0 V _0=\frac{1}{3} RT _0$, the correct match is

    $(1)$ $I \rightarrow S, II \rightarrow T, III \rightarrow Q , IV \rightarrow U$

    $(2)$ $I \rightarrow P , II \rightarrow R, III \rightarrow T , IV \rightarrow S$

    $(3)$ $I \rightarrow P, II \rightarrow, III \rightarrow Q, IV \rightarrow T$

    $(4)$ $I \rightarrow P, II \rightarrow R, III \rightarrow T, IV \rightarrow P$
