Helium is lighter than air and this causes the air to push it up. (just as water pushes up things that are lighter than it i.e. a boat)
This is called buoyancy
they float and pop
Helium
Helium
The game is called Float.
Hot air balloons float because hot air displaces cool air in the atmosphere
Helium is lighter than air. so balloons filled with helium will float in air. warming will make them float or rise up faster.
No, lower temperatures and pressure cause balloons to collapse.
to fly eat balloons as kerby you well unlock the power to float
Helium to get them to float.
The balloons that float usually contain helium in them, which is lighter than air. This enables the balloon to float.
Actually, they do float. They are lighter than air, so they are supposed to float.
Balloons are usually filled with helium gas to make them float. Helium is lighter than air and provides the necessary lift for the balloon to float.
