4. Match the following columns:
\begin{tabular}{|c|l|}
\hline \multicolumn{1}{|c|}{ Process } & First law equation \\
\hline i. Isobaric & a. \( \Delta U = Q \) \\
\hline ii. Isochoric \( q \) & b. \( \Delta U = Q - W \) \\
\hline iii. Isothermal d & c. \( \Delta U = W \) \\
\hline iv. Adiabatic & d. \( Q = W \) \\
\hline
\end{tabular}
a. \( (i-d)(i i-a)(i i i-c)(i v-b) \)
b. \( (i-a)(i i-b)(i i i-b)(i v-d) \)
e. \( ( i - b )( ii - a )( iii - d )( iv - c ) \)
d. \( (i-b)(i i-c)(i i i-c)(i v-d) \)
