What happens when the hot air in the balloon cools?
it goes down
How do you lower a hot air balloon?
There is a flap in the top of the balloon that you open to let the hot air out and the balloon gets lower. Or, you can just wait a little bit, the air cools down, and it goes down, all by itself!
Why a hot air balloon floats?
a hot air balloon floats because of convection which means that the heat that is from the flame goes up than back down than replaces it with cooler air it goes in a cycle.
How does a hot air balloon gain altitude?
Altitude is controlled by the propane burner and the parachute valve. The parachute valve is an opening at the top of the balloon envelope. When closed, it traps hot air from the burner inside the balloon, making the hot air balloon rise. When opened, it allows hot air to escape, and the hot air balloon descends. The reason a hot air ballon rises is because the density of the balloon is less than the density of the surrounding air. Its the same thing as "why does a boat float". In the case of the balloon, the operator modulates the flame on and off to maintain the desired altitude - increase the flame, and the balloon goes up - decrease or shut off the flame, and the balloon goes down. A better metaphor to a boat is a submarine - add ballast and the submarine goes down - blow ballast and the submarine goes up.
What make a hotair balloon go up?
Hot air goes into the balloon. sense the air is so hot, it pushes the balloon off the ground and floats in the air!
Why do hot air balloons travel upward?
The heated air causes the whole balloon to rise. When the air inside the balloon cools down, or when the hot air is let out, the balloon goes down.
What happens when the hot air in the balloon cools?
it goes down
What if the heat source in a hot air balloon goes out?
what goes up, goes down!

How a hot air balloon goes up?
A hot air balloon goes up because the hot air inside is less dense than the surrounding air. Therefore, the hot air rises, bringing the balloon up with it.

What is the current for a hot air balloon?
The current for a hot air balloon is to feel windSlide down for more
Is a hot air balloon an example of convection?
Yes, It is because in a hot air balloon the hot air rises and the cool air falls down.

How do hot air air balloons fly?
In a hot air balloon, a gas burner is used to heat air to a temperature of about 212°F (100°C). Since hot air is lighter and less dense than the cool air around the balloon, the heated air causes the whole balloon to rise. When the air inside the balloon cools down, or when the hot air is let out, the balloon goes down. A hot air balloon is powered by hot air, hot air is lighter (less dense) then the air outside of the balloon (More dense) Heat rises, so the heated air, pushes up into the balloon allowing the balloon to lift. The more heat, the faster it will go, the less heat, the slower it will go, until it starts to descend. Decent is relatively slow, because the air is slowly cooling, however the cooler the air the faster the decent is. To avoid rapid falling, heat it applied to reheat the air so the decent goes slowly.
Why does hot air balloon need fire so that it can fly?
To produce the 'hot air' that goes inside the balloon to make it fly.
