What force holds a hot air balloon in the air?
Buoyancy is what helps hot air balloons float through the air.In order for an object to float it must be surrounded by a denser atmosphere. Balloon pilots control the buoyancy of their balloon by heating the air inside the envelope of the balloon. When air is heated it expands (air molecules expand-becoming less dense) and it also rises when it is surrounded by colder denser air (molecules closer together becoming more dense). These changes in air density is what allow balloons to rise and fall.
Explain in terms of density and Charles's law why heating the air allows a hot-air balloon to float?
i dont know this is my question
Why do hot air balloons float in the air?
Hot air rises and the fire in the hot air balloon wants to go up and float in the air and since it's can't escape the balloon the fire just brings the balloon with it to float in the air
Why will a hot air balloon rise and then float at a certain height in air?
increasing altitude decreases air pressure, this pressure gradient with gravity decides if things sink or float. heating the air in the balloon decreases the weight of the balloon and allows the downward pressure from above plus the weight of the balloon to be less than the upward air pressure from below. hence the balloon rises due to this force imbalance. the balloon reaches a constant height when all three are equal
Can you make a balloon that float in air?
Fill a balloon part way with helium, make an animal out of it and have it float.

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
Why can't a hot air balloon float in outer space?
The key word there is float. There is nothing in space for a hot air balloon to float on.

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.
Why do balloons filled with air not float?
Because air is not as dense as helium filed gallons so they won't float
How does heilum make a balloon float?
Heilum combined with the light material of the balloon make it as light as air making it float.
Can dry ice float a hot air balloon?
No. Dry ice is frozen carbon dioxide, which is heavier than air, so wont float a balloon.
Why would heating the gas in a hot air balloon make the balloon rise?
When the gas (air) in a hot air balloon is heated it becomes less dense. This makes the balloon more buoyant so it rises.Because heating the air inside the balloon makes it less dense than the air surrounding the outside of the balloon, so it will rise.
