The cause of the pressure inside oxygen tanks to change as they are filled is the number of gas molecules changes.
We have to determine what causes the pressure inside oxygen tanks to change as they are filled.
According to the question
The tank is being filled, the number of oxygen particles inside the tank increases so the pressure will also increase.
Pressure is just the force exerted per unit area of the tank by the gas molecules on the walls of the tank.
The oxygen gas pressure inside a tank that has a fixed volume capacity will increase according to the formula of,
[tex]\rm PV = nRT[/tex]
Where P is the pressure, V is the fixed volume of the gas container, n is the number of gas particles inside the container, R is a gas constant depending on the kind of gas and T is the Kelvin temperature inside the tank.
The constant volume and constant temperature, pressure are directly proportional to the number of molecules.
Hence, the cause of the pressure inside oxygen tanks to change as they are filled is the number of gas molecules changes.
