Two rigid tanks are separated by a thin partition. Tank A holds $2\mathrm{.}3$ kg of $R-134a$ at $600$

kPa and $40C.$ Tank B holds $3\mathrm{.}4$ kg of $R-134a$ at $10C$ with a quality of $18\%.$ When the

partition is removed the two sides mix and reach a state of thermal and mechanical

equilibrium. The final pressure at this state is $500$ kPa $.$

What is the quality of the refrigerant at this final state?

What is the amount of heat transferred to the system? $($Use the sign convention

discussed in class; i$.$e$.$ heat in is positive, heat out is negative.$)$
