When an empty tank is filled with air, the air pressure inside the tank is greater than the atmospheric pressure outside the tank. The tank walls are unable to resist the pressure and they rupture, allowing the air to enter and fill the tank.

The Importance of an Empty Tank
When an empty tank is filled with air, it is pressurized. The pressure inside the tank is greater than the atmospheric pressure outside the tank. This difference in pressure causes the air inside the tank to become compressed. The air is forced into and through the tank’s walls and into the engine. The increased pressure in the tank also causes the fuel and air mixture to ignite, and the engine begins to run.
How to Empty Your Tank
When you fill up your tank with gasoline, there’s a certain amount of air that is included. At atmospheric pressure, that air is at a disadvantage because it wants to escape. To keep that air from escaping, the gasoline company puts in a valve called a relief valve. The relief valve is basically a small hole in the side of the tank. When the tank is full, the relief valve opens and the air pressure inside the tank is equal to the atmospheric pressure outside the tank. When you fill up your tank, the relief valve closes and the pressure inside the tank stays the same as the pressure outside the tank.
Now let’s say you want to empty your tank. The first thing you need to do is find the relief valve. Most tanks have a relief valve on the side. If your tank doesn’t have a relief valve, it might have a neck that you can twist to open the valve.
Once you find the relief valve, you need to unscrew it. The relief valve has a spring inside it that keeps it closed. Once you unscrew the relief valve, the pressure inside the tank will go up. The pressure will stay high for a few seconds, and then it will drop. That’s because the pressure inside the tank is now equal to the pressure outside the tank.
When the pressure inside the tank drops, the relief valve quickly closes so that the pressure inside the tank stays the same as the pressure outside the tank
What Happens When You Fill an Empty Tank with Air
When an empty tank is filled with air, the pressure inside the tank is greater than the atmospheric pressure. This causes the tank to rupture, and the air is forced out of the tank in a rush.
The Benefits of an Empty Tank
When an empty tank is filled with air, it creates a bubble of gas exerting pressure on the liquid at the top. The liquid is forced down to the bottom of the tank until it reaches the atmospheric pressure, at which point the gas escapes and the pressure on the liquid is relieved. The sudden release of gas causes a burst of energy that propels liquid up the sides of the tank.
The Dangers of an Empty Tank
An empty tank presents a number of dangers to those inside. For example, an empty tank can easily become inflamed and can burst, spraying hydrocarbons and other dangerous chemicals all over those inside. In addition, the lack of pressure inside the tank can cause the tank to collapse, potentially injuring those inside.
The air inside an empty tank will rise until it reaches the top.
