5-174 A liquid R-134a bottle has an internal volume of 0.001 m. Initially it contains 0.4 kg of R-134a (saturated mixture) at 26°C. A valve is opened and R-134a vapor only (no liquid) is allowed to escape slowly such that tempera- ture remains constant until the mass of R-134a remaining is 0.1 kg. Find the heat transfer necessary with the surround- ings to maintain the temperature and pressure of the R-134a constant.
