1. 10-kg of R-134a at 300 kPa fills a rigid container whose volume is 14 L. Determine the temperature and total enthalpy in the container. The container is now heated until the pressure is 600 kPa. Determine the temperature and total enthalpy when the heating is completed. 2. 10-kg of R-134a fill a 1.348-m rigid container at an initial temperature of -40C. The container is then heated until the pressure is 200 kPa. Determine the final temperature and the initial pressure. 3. A piston-cylinder device contains 0.85 kg of refrigerant-134a at -10C. The piston that is free to move has a mass of 12 kg and a diameter of 25 cm. The local atmospheric pressure is 88-97.6 kPa. Now, heat is transferred to refrigerant-134a until the temperature is 15C. Determine (a) the final pressure, (b) the change in the volume of the cylinder, and (c) the change in the enthalpy of the refrigerant-134a. 4. Water is being heated in a vertical piston-cylinder device. The piston has a mass of 40 kg and a cross-sectional area of 150 cm. If the local atmospheric pressure is 100 kPa, determine the temperature at which the water starts boiling.

Determine the temperature and total enthalpy in the container. The container is now heated until the pressure is 600 kPa. Determine the temperature and total enthalpy when the heating is completed. 2. 10-kg of R-134a fill a 1.348-m rigid container at an initial temperature of -40C. The container is then heated until the pressure is 200 kPa. Determine the final temperature and the initial pressure. 3. A piston-cylinder device contains 0.85 kg of refrigerant-134a at -10C. The piston that is free to move has a mass of 12 kg and a diameter of 25 cm. The local atmospheric pressure is 88-97.6 kPa. Now, heat is transferred to refrigerant-134a until the temperature is 15C. Determine (a) the final pressure, (b) the change in the volume of the cylinder, and (c) the change in the enthalpy of the refrigerant-134a. 4. Water is being heated in a vertical piston-cylinder device. The piston has a mass of 40 kg and a cross-sectional area of 150 cm.
