Why does a balloon filled with helium rise with a balloon filled with an equal volume of average atmospheric air does not?
Helium is less dense than air, so a balloon filled with helium is lighter than the same volume of air. This buoyancy force allows the helium-filled balloon to rise. On the other hand, a balloon filled with air has the same density as the surrounding air, so there is no buoyant force to make it rise.
What is the same about a rock and a balloon?
Both a rock and a balloon have mass and volume. They both occupy space, although a rock is solid and a balloon is filled with gas.
Why does a balloon and the balloon with air weigh the same?
A balloon has a certain weight due to the material it's made of. When you blow air into the balloon, the weight of the air inside balances out the weight of the balloon material, making the total weight of the balloon and air the same as the original balloon.
Which property of a filled balloon would be unchanged on the moon where there's no air and less gravity?
The mass of the balloon and its contents would be unchanged.
What happens when a helium-filled balloon is released and rises into the atmosphere?
As the helium-filled balloon rises into the atmosphere, the surrounding air pressure decreases while the pressure inside the balloon remains the same. This causes the helium inside the balloon to expand, making the balloon increase in size. Eventually, the balloon will reach a point where the difference in pressure between the inside and outside of the balloon will be equal, and it will float at that altitude.
When a balloon is filled with air is heated does the density of the air in the balloon stay the same?
No it decreases

Are helium balloons more dense than air baloons?
No. At the same pressure, a helium filled balloon will be less dense than an air-filled balloon.

Which gas is used to fill a hot air balloon?
A typical hot air balloon is filled with the same air we breath.

The mass of the balloon and its contents would be unchanged.
A balloon is filled with CO2 in the same room on the same day at the same atmospheric pressure a second balloon identical to the first is filled with O2 according to avogadro the experimenters?
The two balloons will have the same number of molecules in them, as they are filled in the same room under the same conditions. Avogadro's law states that equal volumes of gases at the same temperature and pressure contain the same number of molecules.
Is a flat balloon lighter than a air balloon?
depends on mass and if you include the air. same mass and not including the air they both weigh the same, air just expands the balloon and lowers the effect of gravity.

Why does a balloon filled with water neither sink or float and it just drifts and literally becomes one with the water?
The density of water molecules is the same inside the balloon as on the outside.
Why is a balloon heavier when it is blown up with air?
This depends on whether you consider what is inside the balloon to be a part of the balloon, since the weight of the balloon skin will remain the same regardless of what is inside it. If, however, you consider the contents of the balloon to constitute a part of the balloon's mass then it will always be heavier when inflated, regardless of the density of the substance with which it is inflated. However, in this case the density of the balloon will fall when inflated if the contents are less dense than the material of the balloon, which is highly likely since the substance would probably be a gas. Therefore the balloon would be heavier but less dense.
