When you light the burner of a hot air balloon, the balloon itself, the big bag-like part, fills with hot air which is less dense than the air in the surrounding atmosphere. The air being less dense inside means the molecules are spread apart further that normal, so it rises and, being inside the bag-like part of the balloon, it brings the balloon, the basket, and the basket's contents with it.

What gas do we fill in hot air balloon?
Hot air balloons are filled with hot air from a propane burner in the basket. Hot air rises. So provided the cooling air in the balloon is topped up from short blasts from the burner, the balloon will rise off the ground.
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.
Why does the heating of gas cause a hot air balloon to rise?
Because hot air rises and a hot air balloon utilizes this. As the hot air rises it lifts the balloon so that it lifts off from the ground. And the reason why the hot air balloon has a burner, the thing that is connected to the balloon itself and shoots flame into it, is because the hot air inside the balloon begins to cool causing it to fall so the burner reheats the air so that it doesn't return back to the ground.
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 does the burner do to the density of the air in a hot air balloon?
The intense heat of the burner alters the atomic nucleus of the oxygen atom into a synthetic helium atom causing the balloon to rise. The helium atom is less dense than the original oxygen atom.
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.
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 does the burner do to the density of the air in a hot air balloon?
The intense heat of the burner alters the atomic nucleus of the oxygen atom into a synthetic helium atom causing the balloon to rise. The helium atom is less dense than the original oxygen atom.
How does convection in a hot air balloon rise?
In a hot air balloon, convection occurs when the air inside the balloon is heated by a burner, causing it to become less dense than the cooler air outside. As the warm air rises, it creates an upward buoyant force that lifts the balloon. This process continues as long as the air inside the balloon remains warmer than the surrounding air, allowing the balloon to ascend. When the burner is turned off, the air cools, and the balloon gradually descends.
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.
Why does an hot air balloon rise up when you light the burner?
It all has to do with the gas law PV=nRT. When the Temperature "T" increases, the volume of the gas increases which inflates the balloon. It rises because this now warm gas rises through the cooler surrounding air. Warm air rises, cool air sinks
How is heat transferred through the air inside ahot air balloon?
Heat is transferred through the air inside a hot air balloon by convection. The burner at the base of the balloon heats the air inside, making it less dense. This hot air rises and creates lift, causing the balloon to float.
What happens if the air balloon burner was turned off?
The balloon will crash. The burner keeps it up.
