In a hot air balloon air is heated by a flamehow does this enable the balloon to float in the air?

Air, like any other substance has weight, that weight is directly related to its density. The warmer the air is the less dense it is therefore the lighter it is. A balloon full of lighter air will float upward just like a piece of wood in a swimming pool, the wood is less dense than the water.

Do you need helium to make a balloon float?
Yes.
Will ammonia gas float a balloon?
No, the density is too high.
If you wanted to make a balloon float in the air which gas should you use to fill the balloon?
Helium gas is lighter than air and hence balloons filled with helium will float in air.
What would happen if you were to fill a balloon with oxygen?
First, the balloon would float to the ground. After that, nothing special happens to the balloon because you filled it with oxygen.
Can you describe a balloon without using the words float deflate or air?
A balloon is an object that hovers and move with the wind.
Why does a balloon need hot air?
Hot air is less dense compared to cold air. The heated air in the balloon will rise, making the balloon float in the air.to make it rise.
How does a flame enable a hot air balloon to float?
Because it heats the air and of course the hot air will rise above the cold air causing it to float!
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.
What happens to a hot air balloon that allows it to float through the air?
Air inside the balloon is heated. Hot air is less dense than the surrounding air, and thus the balloon rises.
Does a balloon float or sink on water and why?
a balloon float on water
Why does a balloon float in air?
A balloon floats in the air when the molecules inside the balloon are less dense. The gas inside a helium balloon is in essence "lighter" than the air around it, causing a buoyancy effect which makes the balloon float. This can also be seen in hot air balloons when the air molecules are heated by the propane torch and excited, thus creating a less dense environment inside of the balloon compared to outside of the balloon.
How does a hot air balloon float even though it is so heavy?
Well the basic answer is that when the balloon is 'floating' it is not heavy. The hot air inside the balloon is less dense and therefore lighter than the ambient air. The hotter it is, the lighter it is. When the weight loss of the air inside the balloon is equivalent to the weight of the balloon and equipment, passengers, etc., then it will float. The weight reduction of heated air is quite small which is why balloons have to be so big.
Can you make a balloon that float in air?
Fill a balloon part way with helium, make an animal out of it and have it float.
Why can't a hot air balloon float in outer space?
The key word there is float. There is nothing in space for a hot air balloon to float on.
Does a balloon float?
yes
How does the flame in an hot air balloon enable the balloon to float in the air?
The flame heats the air contained in the balloon. This causes the air to expand, thus it becomes less dense than the air surrounding the balloon. Once the air in the balloon is sufficiently less dense than the surrounding air to overcome the weight of the balloons materials, it will lift into the air.
How does heilum make a balloon float?
Heilum combined with the light material of the balloon make it as light as air making it float.
