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
There is no gas that can make humans float in the air naturally. However, helium gas is lighter than air and can be used to fill balloons, causing them to float.
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!
Actually, humans do float. It's just that some of your clothes weigh you down.For the reason on why boats float, it is because the water is denser than the boat filled with air. If you fill a boat with water, then it will sink.

No a train does not float in the air, no train does.

If it were, it would float in air. Does it float in air? There's your answer.

The float has air in it.
Only in water. The air from your mouth is the same density as the air in the room- they will not float in air.
Helium is lighter than air. So it will float in air.
Because it has air in it. Air weighs less than water therefore air floats.
It will float because water has more density than air and barges have air in them
