What are the two forces that affect a hot air balloon?
The downward force of gravity, and the upward buoyant force resulting from the low density air inside the balloon.
Why does a hot air baloon float?
Raising the air temperature inside the envelope makes it lighter than the surrounding (ambient) air. The balloon floats because of the buoyant force exerted on it. This force is the same force that acts on objects when they are in water
What science forces are involved in making a hot air balloon?
The force that lifts a hot air balloon is called buoyancy.
What force makes a hot air balloon rise up into the air?
The upthrust exerted by surrounding air on the balloon.
What force does a hot air balloon use to keep itself in the air?
air pressure
Is a hot-air balloon buoyant?
Yes, hot air balloons are less dense and therefore buoyant ============================================ Hot air balloons are buoyant to the extent that the weight of the hot air in the balloon is lighter than the free air. When the difference is more than the weight of the balloon and its contents it will be buoyant and will ascend.

If you were to turn on the burner on in the hot air balloon what effect would it have on the air in the balloon?
When the burner on a hot air balloon is turned on the air inside the balloon is heated making it less dense. This will cause the balloon to be more buoyant and climb.

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..
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.

What force makes a hot air balloon rise up into the air?
The upthrust exerted by surrounding air on the balloon.
How does hot air balloon work?
the balloon works with the poplo force forcing it up
What force brings the balloon to earth after the hot air is let out?
Force of gravity
What force does a hot air balloon use to keep itself in the air?
air pressure
Why does a hot air balloon float?
Hot air is less dense than cool air, therefore hot air rises to the top of the balloon's envelope, which in turn forces the cooler air out of the bottom. Thus the balloon is filled with air that is less dense than the air outside, creating an upward force upon the balloon. With a balloon of sufficient mass, the balloon can carry the burner, a basket, people and ballast (sandbags). By allowing the air to escape from the top of the balloon, the balloon can gradually descend. If the descent is too rapid for the burner to compensate, ballast can be ejected to slow the descent more rapidly.it floats because the air is pushing it up
