A container equipped with a resistance heater and a mixer is initially filled with 3.6 kg of saturated water vapor at 120C. Now the heater and the mixture are turned on; the steam is compressed; and there is heat loss to the surrounding air. At the end of the process, the temperature and pressure of steam in the container are measured to be 300C and 0.5MPa. The net energy transfer to the steam during this process is

A spherical elastic balloon initially containing 5 kg of ammonia as saturated vapor at 20°C is connected by a valve to a 3-m³ evacuated tank. The balloon is made such that the pressure inside is proportional to the diameter. The valve is now opened, al- lowing ammonia to flow into the tank until the pressure in the balloon has dropped to 600 kPa, at which point the valve is closed. The final temperature in both the bal- loon and the tank is 20°C. Determine a. The final pressure in the tank b. The work done by the ammonia in the process
