when you have helium tank the volume could be X but when you fill a bunch of balloons and you add their volume together, the volume is higher. i need a website link explaining the scientific reason that this happens.

The helium is compressed when it is in the tank. When it exits the tank, it expands in the balloons until it equalizes with atmospheric pressure. Any gas can be compressed, as to occupy a smaller volume. You can see this if you would take a plastic container fill it with air, and submerge it to the bottom of a swimming pool. you would able to see that the container would deform because of the volume change of the container.

helium is a gas
gas can be compressed
depending on the compartment you intend to put it in you can compress helium to a likewise tiny volume.
this compression can be so intense that the gas turns into a liquid
tanks are being used cause their steel walls can hold a a hughe ammount of compressed gas.
once you let it out again like into a ballon its volume returns to the state it normally is: uncompressed.
the wall of the balloon gives helium a likewise lower resistance than steel so it expands as much as it could without being capable to escape and mix with the athmosphere
along with compression gas and tank heat up
while letting it out again tank and gas get significantly cooler
basically this process is used in refrigerators too, but with some other gas.

Helium tanks contains helium as a compressed gaseous liquid forms.Like Liquid Nitrogen.Tank has a liquid solid Helium and balloons have the gaseous volume.If you need more information go to yahoo search and make it yahoo as your default search engine..http://www.yahoo.com.search

gas takes the shape of its containter and the volume of the container is inversely related to the pressure
