Because helium is less dense than air, so it rises.
Hot air balloons rise because heated air from the burner becomes less dense and therefore rises.
Hot air balloons do not use helium; they are typically filled with hot air. Helium is non-flammable and more commonly used in other types of balloons like weather balloons or party balloons. The hot air inside a hot air balloon is what allows it to rise and float.
A helium balloon does not need energy to rise in the air. A hot air balloon needs fuel to rise in air. That is it needs heat energy to rise in air.i love Pizza squares i hope they put helium in then one dayHelium relies on the fact that helium is lighter than air. Hot air balloons rely on the fact that hot air has less volume than cold air and is lighter than the air around it. hot air balloons use hot air to cause the balloon to lift as helium balloons use a special gas to cause lift
No, it is not. "Regular" air is used, and it is heated. Hot air is less dense than cooler air, and it will rise. If hot air is trapped in an envelope, it will give lift to the envelope and an attached payload.
Helium-filled balloons last longer than hot air balloons. Helium is a non-flammable, inert gas that does not expand or contract with temperature changes like hot air does. Hot air balloons require periodic reheating to maintain altitude, whereas helium balloons will gradually lose lift over time but can remain buoyant for days.
Balloons can be filled with air (don't float), or with hydrogen or helium (float because the gas is less dense). Hot air balloons use burners to heat the air so that it becomes slightly less dense than the cooler air around it, providing some lift.
yes honey, that's why hot air balloons rise

Hot air balloons are typically filled with hot air, not helium. The hot air inside the balloon is less dense than the surrounding air, causing it to rise. Helium balloons, on the other hand, are typically smaller and used for decorative purposes or in scientific experiments.

No, hot air balloons are typically filled with hot air to become buoyant and rise. Helium is an alternative gas used in some balloons, like party balloons or weather balloons, due to its lighter weight than air.
they contain helium molecules which are lighter than the air we breath making the balloons rise
Balloons filled with Helium rise because Helium is less dense than normal air. Hot air balloons lift off the ground because heat rises, and when the balloon is full of air of a higher temperature than its surroundings, the balloon will rise.
Helium-filled balloons last longer than hot air balloons. Helium is a non-flammable, inert gas that does not expand or contract with temperature changes like hot air does. Hot air balloons require periodic reheating to maintain altitude, whereas helium balloons will gradually lose lift over time but can remain buoyant for days.
No, hot air balloons, as the name suggests, contain hot air, not helium.
Balloons can be filled with air (don't float), or with hydrogen or helium (float because the gas is less dense). Hot air balloons use burners to heat the air so that it becomes slightly less dense than the cooler air around it, providing some lift.
