Problem 6: BalloonA small balloon is a sphere of the radius 20 cm, and it is filled with the helium gas (monoatomic) atatmospheric pressurep= 100 kPa and a temperature 15◦C. Once we release the balloon it rises rapidlyto an altitude at which the atmospheric pressure drops by 20 %. At that point the balloon breaks. Consider that there is no heat exchange during the process. a) What was the radius of the balloon before it broke?a) What was the temperature at that altitude? Consider the outside temperature was the same asthe temperature inside the balloon.
