What keeps air balloon inflated?
If you mean a hot air balloon, it is the expansion of the air caused by the propane burner. If you mean any balloon, it is the ability of the material to hold the air or gas inside which keeps it inflated.
How does hot and cold air have an effect on an balloon?
If there is warm air in the balloon, cooler air makes the balloon rise and if there is cold air in the balloon warmer air makes the balloon fall.
Why does heating the air in hot air balloon make it rise?
Hot air is lighter than cold air, so cold air sinks and hot air rises; that makes the hot air balloon rise (if the air around the hot air balloon is heated as well, it won't rise, or sink if in the air).
When does a air balloon rise?
A hot air balloon rises because when hot air is added it is intended to rise and when the hot air balloons wants to land, hot air is decreased.
The air in hot air balloon is heated to make the balloon rise?
The volume of air increases on its heating hence the balloon rises on heating
What is the difference in the height of the balloon after ten minutes and the height of the balloon after sixty minutes?
There is no difference at all if the balloon is not inflated or inflated with air.
How many air particles are in a balloon?
That depends on how big the balloon is and weather or not it is inflated with air.
What keeps air balloon inflated?

When an inflated balloon is exposed to cold air?
The volume of the balloon decreases
Would the air in an inflated balloon be potential energy?
i probably wouldn't say the air had potential energy just that an inflated balloon has potential energy.
Why inflated balloon burst if press it hard?
An inflated balloon bursts if it is pressed hard because the molecules inside the balloon squeeze when it is pressed hard and air exerts pressure so the balloon bursts and let the air molecules escape from the balloon.
What happens to a balloon when you fill it with air?
It will fill the balloon and make a oval sphere.
What occurs to the volume of an inflated balloon when exposed to cold air?
It decreases. The colder air contracts, making the balloon shrink.
What is the use of air in air balloon?
with out the hot air the balloon would not rise
Why do you close the mouth of inflated balloon?
The air would escape through the mouth causing the balloon to DEflate
Why does a balloon need hot air?
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.
Why doesnt a balloon float with your air?
The air from your lungs has the same density as the air in our atmosphere. As a result a balloon inflated by a human using their lungs is unable to float.
