yes and so is the air outside the balloon.
Matter is anything that has volume and occupies space. Helium (in balloon) is a gas and has both these properties. So. it is an example of matter.
It was made out of the light gas gas Helium.
Gas. Helium is a gas.
Fill the balloon with a gas which is lighter than air: helium, for example.
No, it is a gas-solid mixture when view as a whole. It has a solid component (the balloon itself), and a gas component (the helium)
Helium. The helium gas in the balloon is lighter than the air outside the balloon.
Inside a balloon there is gas. This gas is normally helium if you want the balloon to fly high, but hydrogen also works.
A helium balloon is made by filling a latex or mylar balloon with helium gas, which is lighter than air, causing the balloon to float. The helium gas is sealed inside the balloon, allowing it to stay afloat for a period of time before slowly deflating.
Helium
Helium is typically pumped into balloons because it is lighter than air and gives the balloon its ability to float.
Helium goes into a balloon to make it float.
Helium which is a lighter-than-air gas, allowing the balloon to float upwards.
