Helium is used to inflate balloons because it is lighter than air and that makes the balloon float.
To make balloons float and to make the pitch of your voice higher ;]
Both are gases.
Yes
Helium is used in various applications such as cooling in MRI machines, for inflating airships and balloons, in welding processes, and in the production of semiconductor devices.
air balloons or hot air balloons fly because they fill with a very light type of air. The air is hot air.
helium is a gas less dense than air.
Water balloons are typically made of thinner material than latex balloons, so they can hold less air in comparison. Also, water balloons are designed to hold water, not air, so they may burst if overinflated with air. Latex balloons are designed specifically for holding air and can typically hold more air than water balloons.
There are traditional hot air balloons, special-shaped hot air balloons (such as animals, objects, or characters), and solar-powered hot air balloons that use solar energy to heat the air inside.
hot air balloons, colorful ones what kind of simple quesion is this!
Heluim is a gas, used for filling up balloons and is also found in space
Hot air balloons float because hot air displaces cool air in the atmosphere
Rubber balloons are more porous than plastic balloons, so they allow air to slowly escape through the surface more easily. This makes rubber balloons deflate faster compared to plastic balloons, which have a tighter seal and are less permeable to air.
