Because hot air rises and cool air sinks. the reason why is because hot air is less dense than cool air so the cooler air will sink

How is a hot balloon lifted into the air?

Hot air balloons like those from "King Tut Balloons" rise because hot air is lighter than cool air. A burner heats the air inside the balloon, making it less dense than the cooler air outside. This causes the balloon to lift gently into the sky, offering a magical flight over stunning landscapes like Luxor’s temples and pyramids.


What is the use of air in air balloon?

with out the hot air the balloon would not rise


Will a balloon rise if the air inside is hot?

The heating of the air through the use of a burner is what makes balloons rise.


What is the difference between a helium balloon and a hot-air balloon?

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


Why the hot air balloon needs hot air to make it rise?

Hot air balloons use hot air because hot air rises above cold air. The air inside the balloon is heated above the temperature of the air outside the balloon. The warmer air trapped inside the balloon then causes the balloon to float above the outside colder air.


What fuel does hot air bloons use?

Hot air balloons typically use propane gas as fuel to heat the air inside the balloon envelope, which makes the balloon rise and float.


What element is used in a hot air balloon?

Hot air balloons typically use propane gas as a fuel source to heat the air inside the balloon envelope, causing it to rise and lift the balloon off the ground.


Which gas do you use for hot air balloons?

Hot air balloons typically use propane gas as a fuel source for the burner that heats the air inside the balloon envelope. The propane is burned to heat the air, which causes the balloon to rise.


What energy does hot air balloon use?

Hot air balloons use the energy generated by heating the air inside the balloon with a propane burner. This heat creates a temperature differential that causes the balloon to rise. As the air inside the balloon cools, it descends, allowing the pilot to control the altitude of the balloon.

Why do you use hot air for hot air balloon instead of cool air?

Hot air is used in hot air balloons because when the air inside the balloon is heated, it becomes less dense than the surrounding cool air, causing the balloon to rise. This buoyancy principle allows the balloon to ascend and float in the sky. Using cool air would not provide the necessary lift for the balloon to fly.


Why do we use warm air in a hot air balloons?

Warm air is used in hot air balloons because it is lighter than cool air, providing the necessary lift for the balloon to rise. As the air inside the balloon gets heated, it expands and becomes less dense than the surrounding air, causing the balloon to float.
