Why does hot air balloon need fire so that it can fly?
A hot air balloon needs fire to heat the air inside the balloon. Heating the air makes it less dense than the surrounding air, causing the balloon to become buoyant and rise. The fire is used to maintain the temperature of the air inside the balloon to keep it flying.
What is the fire inside a hot air balloon called?
The fire inside a hot air balloon is typically fueled by propane and is called a burner. The burner heats the air inside the balloon envelope, causing it to become less dense than the surrounding air and lift the balloon off the ground.
Why is an hot air balloon called a hot air balloon?
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.
Why does the Hot air balloon rise when the fire is lit beneath the balloon?
The fire warms up the air and the air becomes less dense. So the balloon traps the warm air and since less dense gases rise with denser gasses around it, the warm air rises taking the balloon with it.
When does a hot air balloon float highest in the sky?
I think the hotter the fire is ( I'm not really sure on how to make fire hotter! :) sorry!) the higher the balloon goes. because hot air rises and so it seems right that if the air is hotter it will rise higher. if you are reading this answer then, you rock!!

How hot can it get inside a hot air balloon?
It gets super hot in the hot air balloon because of the fire above to make it fly

What happens if you prick the balloon without water?
If you prick a balloon without water, the air inside the balloon will escape rapidly through the hole created by the prick. The balloon will quickly deflate and likely make a popping sound.
Does a balloon without air weigh the same filled with air?
No, a balloon without air would weigh less than a balloon filled with air. The weight of an object is determined by the mass of the object and without the air filling the balloon, there is less mass present, therefore less weight.
How do you make a balloon lift without helium?
There are actually a number of ways to make a balloon lift, without helium. Hydrogen is even less dense than helium (but has the disadvantage of also being highly flammable). And since hot air is less dense than cooler air, you can lift a balloon just by heating air. Since hot air is less expensive than either helium or hydrogen, that is a popular technique.

Can you make a balloon fly without hot air or helium?
Yes, you can make a balloon fly using propellers or an electric motor to provide thrust. By attaching a propeller or motor to the balloon, you can create lift and propulsion to make it fly without the need for hot air or helium.

What happens when you put balloon on top of a fire?
If a balloon is placed on top of a fire, the heat will cause the air inside the balloon to expand rapidly, potentially causing the balloon to burst or pop. The rubber material of the balloon is not flame-resistant and could catch fire. It is not safe to place a balloon on top of a fire.
