Heating causes the air inside the balloon to expand. Some of the warm air leaves through the bottom opening of the balloon, keeping the pressure constant.

Explain how a hot air balloon is lifted from the ground?
In a nutshell, air rises and expands when heated. Through the use of a burner the balloon pilot heats up the air inside the envelope (the balloon itself), this air inside the envelope expands and rises, lifing the basket.
What causes a hot air balloon to rise?
Fire contacting with the air inside the balloon. The heated air within the balloon is less dense than the ambient air surrounding it, therefore for the given volume it is lighter and so rises.
What force makes a hot air balloon rise?
A hot air balloon rises due to the principle of buoyancy. As the air inside the balloon is heated, it becomes less dense than the surrounding air, causing the balloon to float upwards. This effect is similar to how a helium balloon rises in the atmosphere.
How do hot air balloons use air to fly?
Hot air balloons use the fact that hot air rises as a way to make balloons fly. When the air inside the balloon is heated, it rises, and this creates lift which is used to make the balloon fly.
What makes hot air balloon rise?
A hot air balloon rises because the air inside the envelope is heated by a burner, which makes it less dense than the surrounding cooler air. This lower density causes the balloon to float upwards, much like a cork in water.

What causes a hot air balloon to rise?
Fire contacting with the air inside the balloon. The heated air within the balloon is less dense than the ambient air surrounding it, therefore for the given volume it is lighter and so rises.
How does hot air balloon stays up?
The air inside the balloon is heated with a propane burner. As air is warmed, it becomes less dense (lighter) and rises.
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.
What force makes a hot air balloon rise?

How do hot air balloons use air to fly?
Hot air balloons use the fact that hot air rises as a way to make balloons fly. When the air inside the balloon is heated, it rises, and this creates lift which is used to make the balloon fly.
How does a hot-air balloon rise?
The upthrust on the balloon is greater than the weight of the balloon. Thus, it rises upwards. The upthrust on the balloon is greater than the weight of the balloon because the air inside it has a lower density than the surrounding air.
How does a hot air balloon rise in the sky?
A hot air balloon rises in the sky because the air inside the balloon is heated, making it less dense than the surrounding air. This causes the balloon to float upwards, as the less dense hot air inside the balloon is lifted by the denser, cooler air outside.
Why does a gas burner in a balloon begin to rise when heated air is trappd inside the balloon?
The hot air from the gas burner rises and enters the balloon's envelope. Once there is enough hot air trapped, the whole balloon will begin to lift off the floor. This is due entirely to the fact that hot air rises.
What makes hot air balloon rise?
A hot air balloon rises because the air inside the envelope is heated by a burner, which makes it less dense than the surrounding cooler air. This lower density causes the balloon to float upwards, much like a cork in water.
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.
When does a air balloon rise?
A hot air balloon rises because when hot air is added it is intended to rise and when the hot air balloons wants to land, hot air is decreased.
