A player bounces a basketball on the floor, compressing it to 80.0% of its original volume. The air (assume it is essentially N2 gas) inside the ball is originally at a temperature of 20.0oC and a pressure of 2.00 atm. The ball's diameter is 23.9 cm.
(a) What temperature does the air in the ball reach at its maximum compression?
(b) By how much docs the internal energy of the air change between the ball's original state and its maximum compression?
