Current Attempt in Progress

Gas within a chamber passes through the cycle shown in the figure. Determine the energy added to the system as heat during process $\backslash ($ C A $\backslash )$ if the energy added as heat $\backslash ($ Q$\_\{$A B$\}\backslash )$ during process $\backslash ($ A B $\backslash )$ is $19$ J $,$ no energy is transferred as heat during process $\backslash ($ B C $\backslash ),$ and the net work done during the cycle is $11$ J $.$ Use a minus sign to indicate an energy decrease.

$\backslash ($ Q$\_\{$C A$\}=\backslash )$
