Why do hot air balloons float in the ar?
As the air in the balloon is heated, it expands and becomes less dense, or that is, becomes lighter. This then provides lift to the balloon and the basket. The reason the air in the balloon expands, is because as it is heated, the molecules of air move faster and spread out to fill the entire volume of the balloon.
How is air pressure affected when an areas of earth is heated?

How does hot air balloon stays up?
The air inside the balloon is heated with a propane burner. As air is warmed, it becomes less dense (lighter) and rises.
How does the air change as a hot air balloon rises?
As the air in the balloon is heated from the flames, the air becomes lighter. So much lighter than the surrounding air that the balloon eventually rises from the light air in it.
How are temperature and density of air related?
cold air has higher density, by hot air is opposite
Why air rieses when its heated?
Air rises when heated because evaporation has eccord from water reaching its boiling point to evaporating it becomes water vapor and goes up to the sky then it causes presipitation.Then it goes over and over again
