Raising the air temperature inside the envelope makes it lighter than the surrounding (ambient) air. The balloon floats because of the buoyant force exerted on it. This force is the same force that acts on objects when they are in water

How do blimps float?
Just as a baloon does, but the only diffrence it is a much greater mass. And obviously they don't use air, they use helium which is greater then air.
Does a balloon grow when its hot ot cold?
A baloon will 'grow' when the air inside becomes warmer than the air outside. So it grows when it's hot.
Why do hot air balloons float in the air?
Hot air rises and the fire in the hot air balloon wants to go up and float in the air and since it's can't escape the balloon the fire just brings the balloon with it to float in the air
How does a flame enable a hot air balloon to float?
Because it heats the air and of course the hot air will rise above the cold air causing it to float!
Is the air inside the balloon less dense than the air outside the balloon?
No. If you blow air into a baloon, it will be under pressure, and therefore more dense, than the air outside.No. If you blow air into a baloon, it will be under pressure, and therefore more dense, than the air outside.No. If you blow air into a baloon, it will be under pressure, and therefore more dense, than the air outside.No. If you blow air into a baloon, it will be under pressure, and therefore more dense, than the air outside.
How does a hot air baloons fly?
By the hot air that is created from a burner under the envelop (baloon).
Why does a baloon filled with helium float in air but the baloon filled with carbandioxide sink?
Because Helium is less dense than air, and CO2, I assume is more dense
What is it about atmosphere on Earth for balloons to lift?
The earths atmosphere is denser than the helium found in a baloon therefore the baloon is lighter and is lifted above the denser air located in earths atmosphere. Which is why if you just blow up a baloon with air from your lungs it does not float. It would be the same density as the air outside of the baloon.
Why will a helium filled balloon will float in air?
A Helium filled baloon floats in air because Helium is lighter than air. Making it rise to the top of it.
What are the safety features of a hot air balloon?
lots of padding on the inside of the baloon basket ! :)
What is the air of hot air balloon?
It is the same as the air we breath, the only difference is that it has been heated, hot air rises above cold air and thats what lifts the baloon.
Where in the atmosphere do hot air balloons float?
Hot air balloons float because hot air displaces cool air in the atmosphere
How do blimps float?
Just as a baloon does, but the only diffrence it is a much greater mass. And obviously they don't use air, they use helium which is greater then air.
Why was the hot air baloon invented?
So that politicians would have someplace to dispel their internal pressure.
Why does somthing float in air?
Everything lighter than air floats in it. Think of a floating baloon: that is not filled with air as it may look but it's filled with helium, a gas which is lighter than air. If you want to know if something will float or not just check how is its density compared to the air's one. If its lower, it will float.
Does a balloon grow when its hot ot cold?
A baloon will 'grow' when the air inside becomes warmer than the air outside. So it grows when it's hot.
Why can't a hot air balloon float in outer space?
The key word there is float. There is nothing in space for a hot air balloon to float on.
