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.

Why does a hot air balloon rise when the air inside it is heated up?
The hot pressure{air}builds up so the balloon 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!
What if the heat source in a hot air balloon goes out?
what goes up, goes down!
How does air help a hot air balloon fly?
Well the simple and rather obvious answer is that you need air before you can get hot air. To go a little more complex, when you heat air it becomes less dense and therefore lighter, so it rises. That's why air goes up the chimney. Put the hot air in a balloon, the balloon goes up too...........
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.
What causes hot air to rise?
Hot air is lighter than cold air, so it rises up. Ex. A hot air balloon rises up because we heat the air and it goes up.
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.
Why did they call it the hot air balloon?
A hot air balloon is called an hot air balloon because, the inside is heated up to make it less dense, allowing it to rise. Meaning, your heating up the air inside the balloon, hence, the name: Hot air balloon.
What makes a hot air balloon works?
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 .
Why aren't hot-air balloon flights scheduled on hot days?
Because the hot air balloon will keep on going up because the hotter the air gets the higher the hot air balloon will go!
What makes a hot air balloon go up?
ahhh hot air?? hot air rissies sooo when you put hot air nto a balloon it evenually rises
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.
