The hot air is less dense than the air surrounding the balloon, so it floats in the surrounding air.
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.
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.
Hot air rises. That is how a hot air balloon works.
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.
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.
When a hot air balloon is filled with the hot air the air around the balloon is a lot denser. So by convection the balloon rises and the less dense air is replaced by dense air underneath it.
Yes, It is because in a hot air balloon the hot air rises and the cool air falls down.
hot air rises up
D: The hot air inside the balloon becomes less dense than the air outside the balloon.
"Warm air", otherwise known as Hot Air Balloons, float because of one basic Law of Thermodynamics; heat rises. The air in a hot air balloon is hot, therefore, the balloon rises.
A hot air balloon goes up because the hot air inside is less dense than the surrounding air. Therefore, the hot air rises, bringing the balloon up with it.
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.
