A player bounces a basketball on the floor, compressing it to 80.0 of its original volume. The air (assume it is essentially gas) inside the ball is originally at a temperature of 20.0 and a pressure of 2.00 atm. The ball's diameter is 23.9 .What temperature does the air in the ball reach at its maximum compression? Assume that the compression of the air during the bounce is adiabatic.
