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 happens to the hot air balloon when it reaches an altitude of 10000 meters?
the air pressure outside of the balloon decreases.
How would manipulating air temperature allow you to control altitude balloon?
Hot air rises; cold air falls.
Why is a high altitude hot air balloon only partially filled?
As it rises, outside air pressure decreases, and the hot air inside expands and fills the balloon. Same thing is true of large helium balloons.
How do hot air balloon pilots get their balloons back to earth?
What they do is blast cold air into the "hot" air and it makes the air molecules slow down... Thus it makes the air balloon decrease back to earth.
How are lighter than air devices steered?
By wind and altitude is in a hot air balloon the berson in the basket under the ballon will pull the trigger and the hot air will go it the balloon causing it to rise if they want to lowwer they will not pull the trigger
What is the craft that uses heat to gain altitude?
A Hot Air balloon.

A hot air balloon descends 210 feet each minute when landing What is the change in the altitude of the balloon after 3 minutes?
630 feet
How are lighter than air devices steered?
By wind and altitude is in a hot air balloon the berson in the basket under the ballon will pull the trigger and the hot air will go it the balloon causing it to rise if they want to lowwer they will not pull the trigger
How is a hot air balloon able to float with a flame?
As to the reason a hot air balloon floats has already been explained, I will answer your question regarding the flame. The gas burner provides the flame which is placed just in the mouth of the ballon, when lit it provides more heat to the cooling air in the balloon causing the balloon to maintain altitude.
What does a hot air balloon look like on the inside?
A hot air balloon is hollow (naturally) and is filled with the hot air that gives the balloon lift. By surfing the web a bit, one can probably find a picture that gives at least a partial view of the inside. I would doubtless have been taken by someone in the basket of the balloon, but there may be a shot of a an airborne balloon at low altitude taken by someone on the ground.
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.
Why is an hot air balloon called a hot air balloon?
Because the fire or heating device heats the air in the top section ( the actual balloon ) and hot air rises... so the hot air trapped in the balloon makes the balloon rise :)
How is a hot balloon lifted into the air?
to make a hot air balloon rise you use hot air
