Helium is not flammable. However, the cigarette might puncture the balloon.
Helium is less dense than air, which is why the helium-filled balloon floats when you let it go.
Helium is a lighter element compared to air, helium also has fewer molecules than air.
No, I am sorry, but there is no helium inside a hot-air balloon. Instead, there is hot air.
A balloon filled with helium floats and a balloon filled with regular air falls to the ground because helium has less density than air so the air causes the balloon to sink because there are more molecules in it. The helium has less molecules in it so the balloon rises.
A water balloon is filled with water, and other balloons are filled with air or helium.
A helium "balloon" is composed of two parts: the SOLID rubber balloon skin, and the GASeous helium. So the balloon part itself is a solid.
helium in a jar diff from helium atom
It was made out of the light gas gas Helium.
depends how big the helium balloon is and how many
The latex balloon and to a lesser extent mylar, also, is actually porous and has tiny tiny spaces between the latex molecules. The molecules do not fit together with no space between them, and the helium molecules are so small that they are able to fit between the molecules of the balloon and float out and away.
Helium. The helium gas in the balloon is lighter than the air outside the balloon.

A helium balloon does not need energy to rise in the air. A hot air balloon needs fuel to rise in air. That is it needs heat energy to rise in air.i love Pizza squares i hope they put helium in then one dayHelium relies on the fact that helium is lighter than air. Hot air balloons rely on the fact that hot air has less volume than cold air and is lighter than the air around it. hot air balloons use hot air to cause the balloon to lift as helium balloons use a special gas to cause lift
This is a really good question! Helium balloons 'fall' up because helium is lighter than air. In other words, even though gravity is pulling the balloon down, the helium is so light the balloon rises.
The balloon with helium.
Helium is lighter than air. hence helium balloon will float in air.
