By use of the burners. The air is heated and it's density is reduced. Since Hot air is less dense, and therefore lighter than cold air, the balloon rises. It takes a lot of heat to do this, the burners can produce about the same heat output as a 1000 or so cooking stoves with all the rings turned to full power.

How does air density inside a hot air balloon change as the air is heated?
As the air inside a hot air balloon is heated, its density decreases because the air molecules expand and spread out, becoming less concentrated. This decrease in density causes the balloon to become less dense than the surrounding air, allowing it to rise.
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.
How is density related to the flight of a hot air balloon?
Density is inversely related to the flight of a hot air balloon. As the density of the air inside the balloon decreases, it becomes less dense than the surrounding air, causing the balloon to rise. This is because the buoyant force on the balloon is greater than its weight.
When is the density of the air inside a hot air balloon greatest?
The density of the air inside a hot air balloon is greatest when the air inside is coolest. As the air inside the balloon is heated, it expands and becomes less dense compared to the surrounding air, causing the balloon to rise.
Does the air in a hot air balloon increase or decrease its density?
The air in a hot air balloon decreases in density when it is heated. As the air inside the balloon is heated, it expands and becomes less dense compared to the surrounding air, creating lift.

How can a hot air balloon Demonstrate the concepts of Buoyancy and Density?
A hot air balloon demonstrates the concepts of buoyancy and density by using hot air to create a lower density inside the balloon compared to the surrounding air. This lower density causes the balloon to float, as the buoyant force from the surrounding air pushing up on the balloon is greater than the force of gravity pulling it down. This is because the hot air inside the balloon is less dense than the cooler air outside, creating a pressure difference that causes the balloon to rise.
When is the density of a hot air balloon the greatest?
The density of a hot air balloon is the greatest when the air inside the balloon is at its maximum temperature. As the air inside the balloon is heated, it expands and becomes less dense compared to the surrounding air, causing the balloon to rise.
Give three examples where air is pumped in and out to change density?
In the process of inflating a balloon, air is pumped in to increase the density of the balloon. In scuba diving, a diver adjusts the air in their buoyancy control device to control their density and buoyancy in the water. Air is pumped into a hot air balloon to increase its density and provide lift for flight.
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.
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 might limit how high a hot air balloon 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 does density have to do with hot air balloons?
The burners on a hot air balloon create hot air, which rises into the balloon and displaces the cooler air from the balloon. Then the hot air, being less dense, will lift the balloon as the cooler surrounding air sinks below it. Once the air cools, the balloon will lose its lift and settle back to the ground. The hot air is only slightly less dense, so it requires a lot of volume to lift the comparatively smaller mass of the balloon and gondola.
