Analyze how hot air balloon  floats in the air.

It floats in the air because the hot air in the balloon is less dense than the cold air, so it rises.

# data[].attributes.body
Heated air molecules expand and bounce around, and the space becomes less dense than the surrounding space. Increasing the air temperature inside the balloon envelope makes it less dense than the air, making it lighter than air

It floats because the air trapped inside the balloon is heated by a burner, making it “less dense” than the air outside

# data[].attributes.body
The hot air balloon floats and rises in the air because of the hot air it releases, as we know, hot air rises, and therefore the hot air balloon rises when it is heated with the burner. Convection plays a role in the process of hot air balloons. Hot air rises because it’s less dense, while cold air sinks down

Hot-air balloons float because the air trapped inside the balloon is heated up by a burner, making it less dense than the air outside

The balloon part of a hot air balloon is called the “envelope." It is typically made of nylon. Nylon is the perfect hot air balloonmaterial, because it is lightweight, strong, and it will not melt as easily as other materials when heat is applied.

Hot air balloon floats because the air trapped inside the balloon is heated up by a burner, making it less dense than the air around the balloon. As a result, the hot air balloon rises and floats in the sky.

Hot-air balloons float because the air trapped inside the balloon is heated up by a burner, making it less dense than the air outside. Here's another way to think of it. You've probably heard people say that heat rises, by which they really mean that hot air rises.
