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.

Why air balloon come down after some time?
Hot-air balloons function on the principle that warm air rises, and the balloon mechanism holds onto hot air to ascend. Despite this, the hot air can't stay in the balloon forever, the opening at the top of the balloon allowing a slow and steady flow of the hot air out of the balloon and a gentle descent to the ground.
What uses the same principle as a hot air balloon?
A weather balloon filled with hydrogen is also lighter than air, and will rise to great heights.
Why does a hot air balloon fly?
A hot air balloon flies because it is filled with hot air. Hot air rises and causes the balloon to lift from the ground.
Why is an hot air balloon called a hot air balloon?
Because the fire or heating device heats the air in the top section ( the actual balloon ) and hot air rises... so the hot air trapped in the balloon makes the balloon rise :)
What is weight of hot air balloon?
a hot air balloon virtually weighs negative lbs but it would depend on how hot the air is in the balloon.
What scientific principle explains hot air balloon flight?
The scientific principle that allows hot air balloons is the following.It's all in the name: hot air balloon. Hot air is blown into the opening at the bottom of the balloon. Because hot air is less dense than cold air, it rises. Since the balloon becomes filled with air that is less dense that that surrounding it, the balloon rises. If you want to make the hot air balloon rise faster, you have to either put less people in it or weigh it down less with less luggage or extra stuff.

How are the gas laws involved in hot air balloon flights?
because of Archimedes's principle

How is a hot balloon lifted into the air?
to make a hot air balloon rise you use hot air

What is the Tagalog of hot air balloon?
The Tagalog term for hot air balloon is "mainit na palobo ng hangin."

When you heat the air inside a hot air balloon, it rises. Why does this occur?
D: The hot air inside the balloon becomes less dense than the air outside the balloon.
Why does balloon fly?
The hot air inside the balloon expands, making the hot air balloon fly.
