A player bounces a basketball on the floor, compressing it to 80.5 % of its original volume. The air (assume it is essentially N2 gas) inside the ball is originally at a temperature of 20.0∘C and a pressure of 2.00 atm. The ball's diameter is 24.4 cm .

1. well, PV=kT
so PV/T is constant

(2.00)(V)/(20+273.15) = P(0.805V)/(T+273.15)
2.00/293.15 = 0.805P/(T+273.15)
