Hello, Science enthusiasts, today I am here to make you learn about a natural thing happened when a football or bicycle tube punctured. That was if you place your hand at the place where the air is blowing out, then you feel that air is cool in nature.

Many of us love to play soccer. There is also an association for football called “FIFA“. The football world cup is famous all over the world. The only sport most of the people watch is football world cup. The first modern global game of soccer was first codified in 1863 in London.
This soccer is a game is which two opposing teams of 11 players each defend goals at opposite ends of a field having goal post at both ends with points being scored chiefly by carrying the ball across the opponent’s goal line end by place-kicking or drop-kicking the ball over the crossbar between the opponent’s goalposts.
There are world’s famous football players like Cristiano Rinaldo, Lionel Messi, Zlatan Ibrahimovic, Neymar, Gareth Bale, Luis Suárez etc.., Especially children love to play soccer.While we playing if the ball may get punctured by touching to any sharp ends to its surface and when you place your hand at the punctured place you can feel some air is blowing out because the ball is filled with air. If you carefully observe the air which is blowing out will be cool in nature. Did you think why it happens so? Let’s learn the science secret behind it.

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.
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.
