A hot air balloon rises because the air inside the balloon is heated, making it less dense than the cooler air outside. This difference in density creates buoyancy, allowing the balloon to ascend. The pilot can control the altitude by adjusting the temperature of the air inside the envelope; heating it causes the balloon to rise, while cooling it allows it to descend.

Why does a balloon need hot air?

A balloon needs hot air to make it rise because hot air is less dense than cold air. When the air inside the balloon is heated, it becomes lighter and causes the balloon to lift off the ground and float in the air.


What force brings a hot air balloon to earth after the hot air is let out?

Erm.. no.. i believe its Buoyancy... this force causes u the hot air balloon to rise.. not Gravity..


How does a hot air balloon stays in the air?

A hot air balloon can stay in the air because the hot air is less dense than cool air. The hot air that is blown into the balloon causes it to rise and a burner is used to heat the air inside of the balloon to keep it floating.


Why would heating the gas in air balloon make balloon rise?

if you mean how the hot air in a hot air balloon makes it rise, its because hot air is less dense than cold air. when cold and hot air meet the cold air sinks thus making hot air left to rise.so when you put hot air in a balloon the air would rise. hope this helps.


Why are hot air balloons able to rise into the air?

Hot air balloons rise because when the air inside the balloon is heated, it becomes less dense than the surrounding cooler air. This difference in density creates lift, causing the hot air balloon to float upward.


Why will increasing the temperature in a hot air balloon make it rise faster?

Increasing the temperature inside the hot air balloon causes the air inside to become less dense than the surrounding cooler air. This density difference creates buoyancy, making the balloon rise faster.


How does a hot air balloon rise in the sky?

A hot air balloon rises in the sky because the air inside the balloon is heated, making it less dense than the surrounding air. This causes the balloon to float upwards, as the less dense hot air inside the balloon is lifted by the denser, cooler air outside.


What friction aids a hot air balloon?

Friction between the hot air inside the balloon and the balloon envelope helps to create lift by making the balloon envelope less dense than the surrounding air. This difference in density causes the balloon to rise.


Why does a hot air balloon fly?

A hot air balloon flies because hot air inside the balloon is less dense than the cooler air outside. This temperature difference creates lift, allowing the balloon to rise and float in the air. By controlling the temperature of the air inside the balloon, the pilot can control the balloon's ascent and descent.


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 is the use of air in air balloon?

with out the hot air the balloon would not rise
