Thermodynamics: property tables HELP!! 1. The problem statement, all variables and given/known data 1 kg of R-134a fills a 0.14m^3 weighted piston cylinder device at a temperature of -26.4C. The container is now heated until the temp is 100C. Determine the final volume. 3. The attempt at a solution So the boiling point is -26.1, so it is a saturated vapor to a superheated vapor? the specific volume is .14m^3 Pressure is constant? Using a T-V graph? I dont understand how to go about this problem any help would be great!
