Question

A flexible balloon acts in such a way that when pressure exerted, balloon used to be expanded which is directly proportional to the diameter. The balloon is temporarily connected to an air pressure line of 400kPa, 1000C. Air is allowed to fill the balloon until the volume doubles, during which process there is a heat transfer of 50 kJ from the balloon to the atmosphere. Find the final temperature of balloon and mass of air entered in the balloon for the following cases:
a- If balloon contains 1.0 kg air at 100 kPa, 30°C
b- If balloon contains 0.5 kg air at 200 kPa, 30°C

Answer 1

Answer:

By squeezing the balloon, you reduce the space the gas particles can occupy. As the particles are pushed a bit closer together, they collide with more, so the pressure from the moving gas particles increases. ... According to Boyle's Law, the volume of a fixed amount of gas decreases as its pressure increases.
