Many of you may have noticed the phenomenon that basketballs get flat if the weather is cold. If a basketball was inflated to a gauge pressure of 60,000 Pa when the temperature outside was 20∘C, what is the gauge pressure inside the basketball in Pa when the temperature is 10∘C?

Details and assumptions

The outside air maintains a constant pressure of 1 atm=101,325 Pa as the temperature changes.The basketball always has a circumference of 0.75 m.

how?

P1/t1=p2/t2

yeah that's right...p1/t1=p2/t2

don't forget to chaange units

LOL that's on brilliant
