How the Science involved in releasing of cool air from a Punctured football or a bicycle tube:

The reason behind the above practical observation is cleared explained below. When we fill the air in football then more air is stored in less space. So, because of that, the thrust inside the ball is very high. The thrust outside of the football is less than the thrust inside the football. If the air in high thrust area is released into the low thrust area to elaborate, then the temperature of the air is decreased.

Also Learn: Why the air in bicycle tube will reduce frequently in summer?

This same phenomenon is applied to the bicycle tubes. If you observe the air which is released out from the punctured bicycle tube by placing hand, you can sense cool air is emitting. So, this is the reason to emit cool air from the punctured football or a bicycle tube.
