Each country will have its own colour code for gas cylinders, in the UK Helium is currently transported and stored in brown painted cylinders, however the process of changing to conform to new European regulations has already begun, these will eventually be grafite grey, with the cylinder label being the main identification for the gas within.
Helium is colorless.
You have to first obtain a helium tank and then affix the balloon to the nozzle of the tank and turn on the valve, releasing the compressed helium into the container ie. Balloon. But do not leave the tank in direct sunlight, near open flames or sparks and do not shoot it with a Bushmaster ACR battle rifle.
A helium tank is something used to blow balloons and if you put it in your mouth it will make your voice sound squeaky It also is very dangerous at times. it is possible that it can explode if put near fire or heat. BE VERY CAUTIOUS!!!!!!!!!!!!
Green and Black
Generally, they are. There is an international code for them.
The amount of helium in a tank depends on how big the tank is (volume), the pressure of the helium and its temperature. It is calculated from the ideal gas equation with allowance for compressibility.
Helium is colorless.
yes it will, but not by much
A steel tank is hevier than the helium so it holds it down.
what is helium used for
party city Instead of renting a helium tank, why don't you buy one! go for a Disposable helium tank. If you need it for a party this would be the best for you. just go to partybell.com and get one on a lowest price.
Because the particles of helium in the tank are farther apart than particles in the balloon
Because the particles of helium in the tank are farther apart than particles in the balloon
No. Helium is a odourless and colourless gas.

No. Firstly, helium will not explode chemically as it is inert. Secondly, if you wanted to increase the pressure in the tank, you'd have to heat it, not cool it. If the tank material were faulty, it might conceivably crack but in that case the helium would just escape.
The particles of helium are farthest apart in a balloon.
