The density of helium is less than that of air. Due to this reason, balloons filled with helium will float in air.

When you put a balloon in a cold room then in a worm room does its density change?
No. The volume of the helium will change as it expands the balloon due to the increase in temperature. The density of an element never changes. The reason for that is because density is just a fancy way of saying 'The atoms are this far apart' in the equation mass/volume = density.
Why does a helium filled balloon rise in relation to its density?
I'm not sure I understand the question but here goes: Helium is lighter [less dense] than air, so a helium filled balloon rises because it floats up on the more dense air.
Is a helium balloon rising to the ceiling a chemical property?
No. This is because it is demonstrating the fact that it is less dense than the air. Density is a physical property. Therefore the helium balloon rising to the ceiling is not a chemical property, and instead a physical property.
Why would a balloon decrease after being in heat?
less helium..?
How does density of helium compare to density of oxygen and nitrogen?
Helium is lighter (less dense) than oxygen & nitrogen.
Why does a heilum balloon float and not a oxyegen balloon?
because helium has less density
Why does helium rise and regular air sink?
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.
Why does a helium balloon rise in air while ordinary balloon filled with air does not?
A helium balloon rises into the air because the density of the helium is lesser than the density of the air, therefore, the balloon rises, trying to reach above the air. Helium is lighter than air, or to be more precise, less dense. Helium gas weighs less than our atmospheric air so it floats. Same goes for hydrogen and a few other pure gases

Why does a balloon float in the air?
It floats in the air because of the helium inside. Helium's density is less than that of oxygen, same reason fat floats in water.

What makes a helium balloon fly?
A balloon filled with helium flies because helium weighs less than air.
Why do helium balloons rise in air?
The helium balloon rises in air because the density of helium inside the balloon is less than that of the surrounded air that is displaced by the balloons volume. So the balloon is lighter than the surrounding air. Ice cubes float in a glass of liquid water for the same reason.
Why don't normal balloons stay in the sky?
Due to the weight of the balloon. A balloon is merely a capsule full of air so it will fall to the ground as the balloon weighs it down. A helium balloon will rise into the air because helium is less dense than normal air (i.e. it weighs less). The air inside the balloon is the same density as the air outside. The balloon material itself is heavier than air, which causes the balloon to sink. If you decrease the density of the trapped air, such as by heating it or replacing it with hydrogen or helium, the balloon may become even lighter than the balloon material and an equal volume of normal air, in which case the balloon will float or rise.
What has more density air or helium?
The density of helium is less than the density of air. You can infer this without doing any calculations by thinking about the classic example of inhaling the helium from a balloon and talking. Your voice gets squeeky high because helium is less dense than air - that is, your sound waves propagate faster through helium than through air, therefore helium is less dense.

Why wont a blloone with carbon dioxide float?
To float in air, the density of the balloon (divide the combined mass of balloon + contents by its volume) must be LESS than that of the same volume of air. If the gas inside the balloon has a greater density than air, the combined object (balloon + contents) won't have less density than air, either.
