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
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.
Balloons float in the air because they are filled with a gas that is lighter than the surrounding air, such as helium or hot air. This creates a buoyant force that allows the balloon to rise and float.
Hot air balloons float in air due to the principle of buoyancy. When the air inside the balloon is heated, it becomes less dense than the surrounding cooler air, causing the balloon to rise. This is because the less dense hot air creates an upward force that is greater than the force of gravity acting on the balloon, allowing it to float.
Hot air balloons float in the air because the air inside the balloon is heated by a burner, causing it to be less dense than the surrounding cooler air. This temperature difference creates a buoyant force that lifts the balloon. The balloon will continue to rise until the temperature inside equalizes with the outside air, allowing it to maintain a stable altitude.
For a balloon to float in the air, it must be filled with a gas that is lighter than the surrounding air, such as helium or hot air. This creates a buoyant force that allows the balloon to rise and float.
Because Helium is less dense than air, and CO2, I assume is more dense
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.
A Helium filled baloon floats in air because Helium is lighter than air. Making it rise to the top of it.
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.
Hot air balloons float because hot air displaces cool air in the atmosphere
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.
Hot air balloons fly by heating the air within the balloon envelope, which causes it to become less dense than the surrounding air. This difference in density creates lift, allowing the balloon to rise. By controlling the temperature of the air inside the balloon, the pilot can make the balloon ascend or descend.
A hot air balloon requires air to generate lift. In outer space, there is no air or atmosphere, so there is nothing for the hot air balloon to displace to generate lift, causing it to be unable to float.

hot
its hot because that makes it lighter so it can float above air.
