Match the following lists.
\begin{array}{|c|c|c|c|}
\hline & List I & & List II \\
\hline A & \begin{array}{l}\text { Zeroth law of } \\
\text { thermodynamics }\end{array} & 1 & \begin{array}{l}\text { Direction of flow of } \\
\text { heat }\end{array} \\
\hline B & \begin{array}{l}\text { First law of } \\
\text { thermodynamics }\end{array} & \| & Work done is zero \\
\hline\underline{\mathrm{C}} & Free expansion of a gas & III & Thermal equilibrium \\
\hline D & \begin{array}{l}\text { Second law of } \\
\text { Thermodynamics }\end{array} & IV & \begin{array}{l}\text { Law of conservation } \\
\text { of energy }\end{array} \\
\hline
\end{array}
The correct answer is
\(\begin{array}{lccccccccc} & \text { A } & \text { B } & \text { C } & \text { D } \end{array}\)

1. A \(\begin{array} \text { II } & \text { IV } & \text { III } & \text { I }\end{array}\)
2. B \(\begin{array}& \text { III } & \text { IV } & \text { II } & \text { I }\end{array}\)
3. C \(\begin{array}& \text { III } & \text { I } & \text { II } & \text { IV }\end{array}\)
4. D \(\begin{array}& \text { I } & \text { III } & \text { IV } & \text { II }\end{array}\)
