Compute all parts of given question:
Question: A piston cylinder with a set of stops contains 10 kg of R-134a refrigerant. Initially, 8kg of the R-134a is liquid and the rest a gas. At -8C. Heat is then transferred into the R-134a until the piston hits the stops, at which point the volume is 400 L
Part I: Find the temperature of the R-134a when it hits the stops?
Part II: Find the work done during the expansion. Be sure to sketch this on a P-v diagram.
Please give a full detailed explanation of answer for above question.
