look on google =D ..seriously.
helium is less dense than air. :) so helium will float better than air
In helium balloons and blimps. Helium is lighter than air. So balloons or blimps filled with helium will float or rise up
Those balloons are filled with helium gas. Helium is lighter than air. Helium is a noble gas.
Hot air, hydrogen or helium are lighter than cold air.
Helium is lighter than air, hence balloons filled with helium will float and rise up.
because helium is lighter than air
If you want the balloons to float, you would probably use helium.
Helium balloons float in the air because helium is lighter than the surrounding air. This causes the balloon to be buoyant and rise upwards.
Helium balloons float because helium gas is lighter than the surrounding air. This causes the balloon to be buoyant and rise up in the atmosphere.
Helium is lighter than air, so a balloon filled with helium will float. In contrast, air-filled balloons will sink because the density of air is greater than that of helium. Additionally, helium balloons will deflate faster than air-filled balloons due to its smaller molecular size.
The speed at which balloons deflate can vary depending on factors such as the type of material, size of the balloon, and surrounding conditions. Generally, helium-filled balloons will deflate faster than air-filled balloons due to helium being a smaller molecule that can escape more easily. Typically, a helium balloon can start deflating within a few hours to a few days, while an air-filled balloon can last longer.
bcoz helium is lighter than air
