Why hot air balloons rises up in the sky?
Hot air has density less than the air surrounding the balloon. When the average density of the balloon filled with hot air is less than the density of the air outside upthrust is more than the weight of the balloon. therefore it keeps on rising up till the upthrust becomes equal to the weight of the balloon.
How hot and cold temperature affect air balloon?
When the balloon is hot the density of the air in it decreases and hence the upward thrust on the balloon increases and the balloon moves up and viceversa.
What might limit how high a hot air balloon can get?
The density of hot air is lower than air at low altitudes, but the air at higher altitudes is very thin. A hot air balloon can only rise until its density equals the surrounding air.
What is the principle behind in hot air balloon?
Hot gasses are less dense than cooler ones and therefore rise.A hot air balloon rises because the density of the hot air is less than the density of the cold air that it displaces. This causes buoyancy.
What powers hot air balloon?
Hot air balloons are powered by the flame from a propane burner that heats up the air inside the balloon, which lowers the density of the air inside by heating it up and accellerating the particles. Lower density (hot) air will rise above air with higher density (the air outside) which is why they have a height limit, as the average density of air goes down the higher you go.

How do particles make a hot air balloon work?
The hot air has a density under the density of cold air. And so up in the atmosphere.

How is density related to the flight of a hot air balloon?
Density is related to the flight of hot air balloons because the more density the harder it is to get of the ground.
How can a hot air balloon Demonstrate the concepts of Buoyancy and Density?
By rising when filled with lower density (hot) air than that surrounding it.

How does the air density inside a balloon change as it rises from the ground to the air?
The air density inside a balloon changes as it rises because the hot air inside the hot air balloon is less dense than the air around it causing it to fly since hot air rises. But as it rises it loses its hot air causing it to eventually not be able to fly anymore and come down.

What is used to power a hot air balloon?
There is the fire that changes the density of the inside of the balloon causing it to rise.
Does a large rock or a hot air balloon have more density?
as is, a rock, because density is mass over volume and a hot air balloon has a lesser/similar mass (stuff) but is spread out (volume) more than a rock.
