An elastic balloon behaves such that pressure is proportional to diameter and the balloon contains 0.5 kg air at 200 kPa and 300C. The balloon is momentarily connected to an air line at 500 kPa and 1000C. Air is let in until the volume doubles, during which process there is a heat transfer of 50 kJ out of the balloon. Find the final temperature and the mass of air that enters the balloon.After that the air line is disconnected from the balloon and the air is allowed to escape through an opening until the same initial pressure and temperature. For this process, the balloon behaves such that pressure is proportional to squire of diameter. Determine the final mass in the balloon and heat transfer during this process.
