An empty cannister of 0.002 m3 is filled with R-134a from a line flowing saturated liquid R-134a at 0°C. The filling is done quickly so it is adiabatic, but after a while in storage, the can warms up to room temperature, 20degC. Find the final mass in the cannister and the total entropy generation.
I found that the final mass is 2.32kg and that will stay constant even while the can warms up. However, I'm not sure if the final temperature of the can at 20deg will effect the final entropy.
