[tex][/tex] Why helium used in balloons?

Helium is an inert gas, which means that it does not react with other substances. It has the lowest boiling point of any element at -269C and a low density which is why it is used to make items float.

Reasons why it is used in balloons -

• Helium is lighter than air. If you take the same volume of air and helium and weight them on a scale, the helium will weight less. This is because helium is less dense, as helium is lighter than air, a helium balloon rises.
• Helium is a special gas called a Noble Gas, which means it doesn’t burn. When a match is held near a helium-filled balloon, the balloon pops.
