Question $2[5$ points$]$

Consider an isolated flash chamber, as shown below. The refrigerator is not operating right now, meaning not connected to the condenser or expansion valve. The flash chamber just has a total static mass of $1$ kg R$134$a in its volume of $2$ liters at $500$ kPa $.$

For some reason a heat source of $100$ W appears next to it and starts heating it$.$ Instantaneously, the heat source ruptures the chamber wall, letting the vapor escape keeping the pressure inside constant. You are able to contain the leak after $10$ minutes, but some refrigerant is lost. Find the amount of refrigerant lost within that time, initial and final vapor quality, if the pressure of the chamber always stayed the same. Assume that the vapor lost is saturated.

Hint: Mass balance and energy balance connecting initial and final conditions. Do not miss any term.

Total initial $R134$a mass $=1kg$

Total volume $of$ flash chamber $=2$ liters

Pressure $=500$kPa
