A hot air balloon is able to float because the hot air being released into the balloon is less dense than the colder air surrounding it.
Basically, the burner under the hot air balloons fills the balloons with hot air, enabling the balloon to rise through the cooler air outside.
warm air
Hot air rises and the fire in the hot air balloon wants to go up and float in the air and since it's can't escape the balloon the fire just brings the balloon with it to float in the air
Usually only balloons that are filled with helium will float. Helium is a gas that is lighter than air, so causes the balloon to fly. Note that if you blow a balloon yourself, it will just float to the ground. There are also hot air balloons in which the air is heated by an on board heater. Hot air, being lighter than cold air, rises and lifts the balloon. When the air cools, unless it is reheated, the balloon descends.
Hot air is less dense compared to cold air. The heated air in the balloon will rise, making the balloon float in the air.to make it rise.
Because it heats the air and of course the hot air will rise above the cold air causing it to float!
A balloon floats in the air when the molecules inside the balloon are less dense. The gas inside a helium balloon is in essence "lighter" than the air around it, causing a buoyancy effect which makes the balloon float. This can also be seen in hot air balloons when the air molecules are heated by the propane torch and excited, thus creating a less dense environment inside of the balloon compared to outside of the balloon.
Hot air. That's what makes it float.
The key word there is float. There is nothing in space for a hot air balloon to float on.
Well it has a gas fueled flame and the flames heat makes the balloon part fill up with hot air. Hot air rises so the hot air balloon will float into the sky like a helium balloon would.

hot
Going up!Hot air is actually less dense than cold air. So, in turn the hot air rises causing the balloon to float up.Because hot air has a lower density than cold air, causing hot air to rise. When the hot air is trapped in a balloon, the push of the rising air causes the balloon to float.
They are filled with hot air. The hot air raises and take the balloon with it

"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.
Hot air is less dense compared to cold air. The heated air in the balloon will rise, making the balloon float in the air.to make it rise.
Air inside the balloon is heated. Hot air is less dense than the surrounding air, and thus the balloon rises.
a hot air balloons floats. something to do with buoyancy
