A gas burner is used in the hot air balloon to heat air. When heat is applied, particles tend to expand. Due to this the air surrounding the balloon is cooler than the air inside it, making it to rise.
A hot air balloon is normally powered with propane. Other than that, it is just ordinary air used inside the balloon.
They move around faster and faster, causing the temperature to increase, and because hot air rises above cold air, the balloon lifts, applying lift to the basket, causing the hot air balloon to rise into the air.
Hot air balloons get their buoyancy from hot air created by a propane burner at the base of the balloon. Hot air is less dense than cold air and so weighs less. When the cold air that is displaced weighs more than the balloon, the balloon will rise. The balloons weight is controlled by turning the burner on and off when needed. The hot air is less dense than the outside air and so the balloon is squeezed upwards by the surrounding air. The air becomes less dense as more heat is applied, particles separate more and more when heat is applied. The more heat is applied the further apart and less dense the particles become.
In a liquid (as solid particles in a liquid or in a lava lamp with two immiscible liquids) In the air, hot air rises, cold air descends (as in a hot air balloon)
it rises

Hydrogen is used. Sorry. Just regular air is used in a hot air balloon, it is heated which makes it lighter and less dense and therefore provide lift. Hence the name hot air balloon. Hydrogen is used in a gas balloon.

A typical hot air balloon is filled with the same air we breath.
A hot air balloon can stay in the air because the hot air is less dense than cool air. The hot air that is blown into the balloon causes it to rise and a burner is used to heat the air inside of the balloon to keep it floating.
The hot air has a density under the density of cold air. And so up in the atmosphere.

they slow down
no, hot air air is used
In hot air, particles are moving faster due to the increase in heat. This makes hot air lighter than cold air so the hot air will rise. When you put hot air into a balloon, the hot air will try and rise to the top. This allows the balloon to float in the air. Eventually the air will cool and sink back down which is why it's important to continuously pump hot air into the balloon to keep it up. Hope this helps! :)
