Hey, baseball world: We here on the NFL side are sorry to see your game engulfed in a cheating scandal. At its core, Deflategate suggested that the New England Patriots used an illegal process for lowering the inflation of game footballs at the behest of quarterback Tom Brady, who preferred the grip of softer balls.

Air molecules don’t bounce around as much in the cold as they do in warm weather. Inside a football, air molecules bounce around and collide with the interior walls of the ball (bladder, really). The air’s pressure inside a football will go down with temperature. The pressure that must be used is the total pressure.

The NFL requires that all game footballs be inflated to a pressure between 12.5 and 13.5 pounds per square inch (psi), and that they weigh 14 to 15 ounces (397 to 425 grams), ESPN reported.

Nitrogen

Association football Law 2 of the game specifies that the ball is an air-filled sphere with a circumference of 68–70 cm (27–28 in), a weight of 410–450 g (14–16 oz), inflated to a pressure of 0.6 to 1.1 atmospheres (60–111 kPa or 8.7–16.1 psi) “at sea level”, and covered in leather or “other suitable material”.

Tire Pressure Air, the standard gas used to fill car tires, is comprised of 78 percent nitrogen. The rest of the gas is made of approximately 21 percent oxygen, water vapor, carbon dioxide, and smaller concentrations of miscellaneous noble gases such as neon and argon.

Nitrogen gas

With air, the shock is absorbed, allowing for a much smoother ride. Besides this, solid tires would cause more friction, which in turn means the treads would wear out much quicker (tire tread wear is the reason we replace our tires).

The Nitrogen Advantage Nitrogen molecules are larger and slower moving than those of compressed air. Because of this, nitrogen won’t seep out of your tires as quickly as air will, helping to maintain proper pressure for a longer period of time. The benefits of proper tire pressure are numerous.

Disadvantages of Nitrogen:

• Nitrogen inflation is quite costly when compared to oxygen.
• Maintenance of nitrogen filled tyres is also quite tricky because once you have filled nitrogen inside your tyres, it is necessary that you have to use only nitrogen whenever you are up for an air filling.

Since nitrogen molecules are bigger than normal air molecules, it is harder for them to leak out. This means a tire filled with nitrogen will maintain air pressure longer. Therefore, they say, you’ll roll on tires that are always properly inflated, resulting in better fuel economy and longer tire life.
