A rigid, sealed container of R134a initially at -30°C and 40% quality is placed inside a room so that it heats up at 5°C/hr. If there is 3 kg of R134a in the container, determine:
a) The volume of the container
answer must be 0.2723 m3
b) The specific volume of the vapour when the R134a finishes converting into a gas
answer must be 0.09075 m3/kg
c) The pressure when all the R134a has finished converting into a gas
answer must be 222.8 kPa
d) The energy required to turn all the R134a into a gas
answer must be 399.6 kJ
e) How long it will take for all the R134a to become a gas
answer must be 4.52 hrs
