MATCH THE COLUMN
Find the change in the internal energy of the system in each of the situation in column-I and match the appropriate value of energy in column-II
\begin{tabular}{|l|l|l|l|}
\hline \multicolumn{2}{|c|}{ Column-I } & \multicolumn{2}{c|}{ Column-II } \\
\hline A. & \( \begin{array}{l}\text { A system absorbs } 500 \mathrm{cal} \\
\text { of heat and at the same } \\
\text { time does } 400 \text { J of work. }\end{array} \) & p. & \( 1680 \mathrm{~J} \) \\
\hline B. & \( \begin{array}{l}\text { A system absorbs } 300 \mathrm{cal} \\
\text { and at the same time } 420 \mathrm{~J} \\
\text { of work is done on it. }\end{array} \) & q. & \( -5000 \mathrm{~J} \) \\
\hline C. & \( \begin{array}{l}1200 \text { cal is removed from } \\
\text { a gas held at constant } \\
\text { volume. }\end{array} \) & r. & \( 1692 \mathrm{~J} \) \\
