When soccer balls and basketballs are left out in the cold they go flat. When the gas in a balloon is cold, the molecules have less energy, move more slowly and don’t collide as hard or as often with the side of the ball. The ball decreases slightly in size and it becomes flat.
Why did the soccer ball deflate in cold temperatures?
As the temperature decreases, gas molecules contract and move around more slowly with less energy. Thus, lower pressure leads to a lower bounce of the ball. That’s why a fully-inflated ball might appear deflated if the temperature drops dramatically.
Why do footballs deflate during the winter?
When temperatures change by a factor of 10℉, pressure changes by a factor of 1 PSI. This means that an inflated football can actually lose pressure and become slightly smaller and under-inflated when the weather gets colder.
Why is my soccer ball deflating?
Soccer balls lose air pressure over time. Sometimes over a few days (soccer balls that use butyl bladders keep air pressure longer than balls that use latex bladders). Be sure to check the pressure frequently to make sure the ball is properly inflated.
How does temperature affect a soccer ball?
This is because the gas molecules inside the ball expand as temperature increases. As the gas molecules expand, their energy increases and they bounce around faster inside the ball. That’s why higher pressure leads to a higher bounce of the ball. Likewise, a lower temperature will lead to a lower pressure.
Does deflating a football make a difference?
In the end, the reason for deflating a football owes more to physiology than physics. A slightly deflated ball is a bit softer, making it easier to grip the ball to throw it and reducing the bounce when it hits the hands of a receiver, making it easier to catch.
Why do balls bounce higher when heated?
When the ball is heated, it becomes more elastic, as the bonds are able to move more freely and thus are able to stretch more than those in a cooler ball, and thus less energy is lost (Portz, 2011). This then means that the ball bounces higher.
Is a deflated football easier to throw?
Background. The official rules of the National Football League require footballs to be inflated to a gauge pressure between 12.5 to 13.5 pounds per square inch (86 to 93 kPa) when measured by the game officials. … Removing air from a football makes it easier to grip, throw, and catch.
Does cold weather affect football games?
Cold weather affects, first and foremost, the football itself. The air pressure of a football is reduced by 20% in cold weather. Many footballs are inflated indoors, then brought into the cold, so the pressure in those footballs may drop during the game.
Does the amount of air in a football affect how far you can throw it?
Having an under-inflated ball also allows quarterbacks to throw the ball farther, Tompkins explained. When developing the grip for Baden’s footballs, the company’s R&D team found that by adjusting the RPM of a spiral from 5,400 to 7,200, it made a difference of four feet in distance traveled.
Does deflating a soccer ball damage it?
The most important thing to remember when deflating a soccer ball, no matter which method you use, is to avoid damaging the internal bladder of the ball. To protect the internal bladder, the air must be released at a slow, even pace to protect the integrity of your ball.
How do I keep my soccer ball from deflating?

How does weather affect soccer?
Heavy rainstorms greatly affect a soccer pitch, especially if it’s natural turf. Substantial rainfall can create puddles, muddy areas, and sinkholes on soccer fields. These change the game in a few ways. … Soccer players often complain that the ball moves too fast when turf is wet.
Does a softball travel farther in hot or cold weather?
In baseball, the ball travels much better when its hot and humid which is a proven fact because warm air is less dense than cool air and therefore there is less resistance on the ball as it travels in the air, same with humid air being lighter than dry air.
What are some other factors that could affect air pressure in the footballs?
Changes in temperature, evaporating rain, and barometric pressure affect the pressure inside the football.
