Gas Pressure
Gas Pressure
gas pressure
The pressure in a container is due to the particles of the gas hitting the inside walls of the container.
Helium is a gas and will take the shape of the container it is taken
Pretty much nothing. It'll mix with the atmosphere and diffuse. Not a problem unless you have huge amounts in a closed, small space.
depends on the size of its container and volume of helium filling it
Of course. What a strange question! It implies that helium may be able to keep in a shape that is not the same as its container and thefore leave a vacuum in parts of the container.
put it in a metil container
If the lid is removed from a container holding helium gas, the helium will escape into the surrounding environment since helium is lighter than air. This can result in the helium dispersing quickly due to its low density compared to the air around it.
No, helium has weight, but it rises when its in an expandable container such as a balloon because it is lighter than the nitrogen rich atmosphere but inside of a rigid container the helium can only add weight. (see the mythbuster's episode about the helium football)
Helium at room temperature is a gas. You can certainly put your hand in a container of helium and touch it although you would not feel anything.
You don't have to find the volume ! If gas is put into a closed container, it fills it. The volume of gas in a one liter tank is one liter.
