I am choosing to study how the PSI (pounds per square inch) of a football is affected by the temperature. I chose to study this because I like football and I always pondered this question. I believe that this is a worthwhile question to study because these studies can help improve the game as the weather gets colder. As air cools‚ it expands‚ so when a football gets colder‚ the air inside it expands. This expansion causes the air pressure to decrease. The air pressure decreases because the molecules
