4. One kilogram of R-134a fills a 0.14-m weighted piston-cylinder device at a temperature of -26.4 °C. Determine the total enthalpy in this container. The container is now heated at constant pressure until the temperature is 100 °C. Determine the final volume and total enthalpy of the R-134a when the heating is completed. Show this process on a P-u diagram with respect to saturation lines. R-134a -26.4°C I kg 0.14 m
