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.

What happens to volume and mass in a hot air balloon?
When the air is heated inside the balloon, it expands, causing it to be lighter than the surrounding (and presumably) cooler air. One imagines however, that as the air inside the balloon is heated, some air is forced out (due to expansion), thus resulting in a decrease in the entire apparatus' overall mass (not to mention a decrease in mass due to any fuel's having been used to heat the air in the balloon).
Do you need helium to make a balloon float?
Yes.
How do particles make a hot air balloon work?
Particles in the air are heated by a burner in the hot air balloon, causing them to expand and become less dense. This creates a pressure difference between the inside and outside of the balloon, allowing it to rise and float in the atmosphere.
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.
Will ammonia gas float a balloon?
No, the density is too high.
Why does an air balloon not float?
A hot air balloon floats because the air inside is heated, making it less dense than the cooler air outside. This creates a buoyant force that lifts the balloon. If the air inside the balloon is not heated, it will not be less dense than the surrounding air, and the balloon will not float.
Why does a balloon need hot air?
A balloon needs hot air to make it rise because hot air is less dense than cold air. When the air inside the balloon is heated, it becomes lighter and causes the balloon to lift off the ground and float in the air.
In a hot air balloon air is heated by a flame Explain how this enables the balloon to float?
Heating the air inside the balloon makes it less dense than the surrounding air, causing the balloon to float upwards. As the air inside the balloon cools, it becomes denser and the balloon descends. The pilot can control the altitude by adjusting the temperature of the air inside the balloon.
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 particles used in hot air balloon?
In a hot air balloon, the particles refer to the air molecules inside the balloon that are heated by the burner. When the air molecules are heated, they become less dense and rise, creating lift for the balloon. This process allows the hot air balloon to float in the cooler, denser air around it.
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.
How does the air inside a hot air balloon help it to become light and float in the sky?
The air inside a hot air balloon is heated by a burner, which makes it less dense than the surrounding cooler air. This difference in density creates lift, allowing the balloon to float in the sky.
What makes a hot air balloon float?
A hot air balloon floats because the air inside the balloon is heated, which makes it less dense than the surrounding air. This lower density air creates lift, allowing the balloon to rise. The balloon will continue to float as long as the air inside remains heated.
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!
Does a balloon float or sink on water and why?
A balloon filled with air will float on water because it is less dense than water. The buoyant force acting on the balloon allows it to float.
What is the buoyant force of a hot air balloon?
The buoyant force on a hot air balloon is equal to the weight of the air displaced by the balloon. When the air inside the balloon is heated, it becomes less dense than the surrounding air, causing the balloon to rise. The buoyant force allows the balloon to float in the air.
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.
