An empty propane tank is brought to a filling sta9on to be reloaded. The tank is a standard\ barbeque tank of dimensions 12 diameter by 18 tall, giving a total volume of 2035 in 3 or\ 0.0333 m3 . The empty tank contains saturated propane vapor at 20\\\\deg C. The filling sta9on\ provides saturated propane vapor at 25\\\\deg C to the tank. As the tank fills, it rejects heat to the\ environment at 20\\\\deg C to allow the condensa9on of propane to liquid in the tank. The tank\ itself remains at 25\\\\deg C throughout the filling process. The filling ends when the tank contains\ 90% liquid by volume and 10% vapor.\ (a) Find the pressure in the tank at the end of the filling (kPa), and the mass of propane that\ was added (kg).\ (b) Find the amount of heat that was rejected from the tank to the environment during the\ filling process\ \
