What happens to air in a balloon?

it slowly leaks out of the balloon, to equalize oxygen and Co2 levels.


What does density have to do with hot air balloons?

The burners on a hot air balloon create hot air, which rises into the balloon and displaces the cooler air from the balloon. Then the hot air, being less dense, will lift the balloon as the cooler surrounding air sinks below it. Once the air cools, the balloon will lose its lift and settle back to the ground. The hot air is only slightly less dense, so it requires a lot of volume to lift the comparatively smaller mass of the balloon and gondola.


Why does a hot air balloon fly?

A hot air balloon flies because it is filled with hot air. Hot air rises and causes the balloon to lift from the ground.

Can a hot air balloon lift a car?

yes


Why is the size of balloon in the hot air balloon important?

Big enough to allow the hot air to create lift.


How much hot air does it take to raise a hot air balloon?

No set answer to that, it depends on how much the balloon has to lift.


Why does an air balloon float?

If you mean hot air balloon then it floats because hot air rises because it is less dense and with enough hot air caught in the balloon it can lift create enough lift to take off into the air. If you mean a helium balloon then it rises because helium in the balloon is less dense then the air around it. Since less dense things rise to the top the balloon will float.


Why does the hot air balloon come down?

Once the air cools, the balloon will lose its lift and settle back to the ground.


How does a hot air balloon lift of the ground?

You have to trigger the heat, which goes through the tube and it heats the balloon and it flies in the air.


How does a hot air balloon return to Earth's surface?

A hot air balloon comes down when less lift is provided by reducing balloon air temperature to control descent.


Why does a hot air balloon only go up when it is hot air?

Hot air is less dense then the surrounding air, meaning it's lighter then regular air, allowing it to naturally lift. If something catches that lifting air, and the air is so light that it can lift the required weight up, then it will lift. That's why a hot air balloon requires hot air to lift.
