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.
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.
when you but the bottle in hot water the balloon particles push apart and cause expansion
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
they slow down

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! :)
turds
the particles begin to slow down and relax releasing the lift of the balloon at a slow rate which is why its safe to ride.
Air inside the balloon is heated. Hot air is less dense than the surrounding air, and thus the balloon rises.
it pops
A hot air balloon would not work on the moon.
The hot air has a density under the density of cold air. And so up in the atmosphere.
the air pressure outside of the balloon decreases.
it goes down
