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.
