The hot air from the fire pushes the balloon up, and putting out the fire makes it go down again :)
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.
The entire balloon is called the Envelope and makes up the top part of the hot air balloon. The deflation Port is located at the very top of the envelope and allow the operator to release the hot air in the balloon to decrease the balloon's buoyancy and make it sink.
A hot air balloon is called such because it is filled with hot air to make it rise. When the air inside the balloon is heated, it becomes less dense than the surrounding cooler air, causing the balloon to float upwards.
A hot air balloon rises because the air inside the envelope is heated by a burner, which makes it less dense than the surrounding cooler air. This lower density causes the balloon to float upwards, much like a cork in water.
Propane. This is what makes the flame that heats the air in the balloon.
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.
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.
Heat rises of it makes the ballon rises
Hot air makes a hot air balloon rise because hot air is less dense than the cooler air around it, so the hot air balloon floats on the cooler air around it.
The current for a hot air balloon is to feel windSlide down for more
In hot air, particles are moving faster due to the increase in heat. This makes hot air lighter than cold air so the hot air will rise. When you put hot air into a balloon, the hot air will try and rise to the top. This allows the balloon to float in the air. Eventually the air will cool and sink back down which is why it's important to continuously pump hot air into the balloon to keep it up. Hope this helps! :)

The upthrust exerted by surrounding air on the balloon.
bust the balloon
a hot air balloon works when the hot air blowing from the bottom pushes up the balloon which lifts it up into the sky where it moves in the direction where the wind blows .
Hot air balloons go down by releasing the hot air in the balloon. Normally you just let the air inside cool and descend slowly. You release hot air only if you wish to descend more quickly.
