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.

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!
Does a hot air balloon float or fly?
a hot air balloons floats. something to do with buoyancy
Why does a hot air baloon rise?
They rise because the hot air from the fire in the balloon art weighs less then the cool air around the balloon. so it floats up and rises. It uses convection energy. Hot air is less dense and rises and cool air is more dense and sinks.
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.
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.
How a hot air balloon rises?
The hot air is less dense than the air surrounding the balloon, so it floats in the surrounding air.

Hot air makes hotairballoons do what?
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.
What is a man made device that floats on air because the air inside if it is heated?
Hot air balloon.
What floats in air?
A balloon.
Why does hot air balloons float?
To put it simply, hot air balloons rise due to heat produced by the burning of propane, the heat travels up through the balloon's valve into the balloon itself (the envelope) and up to the parachute valve. Since heat rises, the hot air balloon its self rises. Better answer: a boat floats on water because it weighs less than the water it replaces. likewise, a hot air balloon floats, because the weight of the total balloon + hot air is less then the volume of cold air it replaces. Air has a weight too, but normally you don't notice.
How hot air baloons are able to float?
hot air baloons are able to fly because the hot air that is released in to the ballon wants to get out so there for it keeps pushing and that is how a hot air balloon floats
Why does a hot air balloon that is so heavy float in the air?
Hot air is less dense than cold air so it floats upwards. If you encapsulate this hot air with a bag and the lift produced exceeds the mass of the bag, the bag or balloon will be carried up with the hot air too.
Why does an air balloon float?
If you mean hot air balloon then it floats because hot air rises because it is less dense and with enough hot air caught in the balloon it can lift create enough lift to take off into the air. If you mean a helium balloon then it rises because helium in the balloon is less dense then the air around it. Since less dense things rise to the top the balloon will float.
How the hot air balloon can rise up into the air even through it doesm't have a motor?
A rubber ball rises up in the water because it is full of a substance (rubber) that is lighter than the same volume of water. A hot air balloon rises up into the cool air because it is full of a substance (hot air) that is lighter than the same volume of cool air. The hot air balloon floats in cool air, just like the rubber ball floats in water.
Does the lift depend on the surface area of the hot air balloon?
Yes it does, it also depends on how big the are inside the balloon is too. because think of a chinese lantern, as this floats to the sky using the hot gas from the fire, now think of a hot air balloon in the same way :)
