The gravitational attraction of the Earth keeps the atmosphere from floating off into space
When balloons float they have helium in it. Helium is not air, but a gas. It's lighter than air, which makes it float.
things float in air because of density
Hot air rises and the fire in the hot air balloon wants to go up and float in the air and since it's can't escape the balloon the fire just brings the balloon with it to float in the air
Because it heats the air and of course the hot air will rise above the cold air causing it to float!
The air from your lungs has the same density as the air in our atmosphere. As a result a balloon inflated by a human using their lungs is unable to float.
The key word there is float. There is nothing in space for a hot air balloon to float on.

A whole chili pepper contains an air space, so will float on water.

They float around in Space
to help it to float on water.
To float in air is to leave the ground. As the atmosphere stretches from the ground to the edge of space, I would say we were submerged in air.
It will float in space and remain the same as it is.
A space shuttle is able to float because there is no gravity in space.
Yes everything will float in space, as there is no gravity.
A whole chili pepper contains an air space, so will float on water.
There is an small air space in eggs. The space is too small to let the egg float in fresh water. An addled egg may have formed enough gas, due to decomposition, to cause the egg to float.
