Particles in air, when heated go further apart than they already are thus becoming less dense and the colder denser air is heavier than the heated air.
So the hot air rises when the cold air sinks
This is also why people are most likely to get a headache in cold weather

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.
How is convection used in hot air balloons?
Hot air rises because it occupies a greater volume per unit mass of air than cooler air, this makes it less dense. A hot air balloons fire generates hot air which floats inside the balloon, causing it to rise.
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.
Does Archimedes principle can also be applied to gases?
Yes. That's the entire basis of convection. A balloon full of hot air floats in cold air.
What is the scientific reason an air mattress floats on water?
Because the air contained inside the matress is lighter than the water, it floats. same reason why Helium, which is lighter than the rest of the air around it, floats as well when it is in a balloon.
Does a hot air balloon float or fly?
a hot air balloons floats. something to do with buoyancy
What vehicle that can floats in the air?
Hot air balloons, sail planes, kites.
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.
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.
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.
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
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!
The smoke from a bonfire rises upwards?
It is hot, and less dense than the air it displaces. It floats of the cooler, denser air.
The smoke from a bonfire rises upwards why?
It is hot, and less dense than the air it displaces. It floats of the cooler, denser air.
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.
