When a system is taken from state $\backslash ($ a $\backslash )$ to state $\backslash ($ b $\backslash )$ in the figure $($Figure $1)$ along the path $\backslash ($ a c b$,88\mathrm{.}0\backslash$mathrm$\{$~J$\}\backslash )$ of heat flows into the system and $63\mathrm{.}0$ J of work is done by the system.

Part A

How much heat flows into the system along path $\backslash ($ a d b $\backslash )$ if the work done by the system is $13\mathrm{.}0$ J $?$
