$\backslash$#$3$ An ideal gas with a fixed number of molecules undergoes the three processes described below. For each, fill in the table giving whether each quantity or change in that quantity is positive $(+),$ negative $(-),$ or zero $(0).$ You must explain how you determined your answer for full points.

$($a$.)$ Use the information from the tables to sketch each process's $\backslash ($ p V $\backslash )$ diagram. Start each process from the same point labeled $\backslash ($ i $\backslash )$ in the diagram. You don't have enough information to exactly determine the final state, but you should be able to determine a possible final state. Use the isothermal graph provided as a guide to find the final state.
