R-134a is contained in a vertical cylinder fitted with a frictionless piston and a set of stops and the volum is 0.05m^3 when the piston is against the upper stops. The pressure of the R-134a must be 200kPa to support the piston when it is not pushed against the stops. Initially the R-134a in the cylinder is at 200kPa, 40% quality and occupies a volume of 0.03m^3. The R-134a is then heated to a final temperature of 30 degrees centigrade. Determine whether or not the piston reaches the stops.
