Hot air is less dense than cool air, therefore hot air rises to the top of the balloon's envelope, which in turn forces the cooler air out of the bottom. Thus the balloon is filled with air that is less dense than the air outside, creating an upward force upon the balloon. With a balloon of sufficient mass, the balloon can carry the burner, a basket, people and ballast (sandbags). By allowing the air to escape from the top of the balloon, the balloon can gradually descend. If the descent is too rapid for the burner to compensate, ballast can be ejected to slow the descent more rapidly.
it floats because the air is pushing it up
A hot air balloon floats because the hot air inside the balloon is less dense than the cooler air outside. This temperature difference creates buoyancy, causing the balloon to rise. By controlling the temperature of the air inside the balloon, the pilot can control the altitude of the balloon.
It is because helium is 6x lighter then air, therefore helium filled balloons float. Hot air balloons float because hot air rises. (because it's lighter than normal/cold air)
Answer:Hot air balloons are filled with hot air (that's pretty obvious) and are surrounded by cooler air. Cooler air is more dense than hot air so the balloon weighs less than the air it displaces. This gives it a buoyant upward force. This is the same as holding a pop bottle filled with air under water. Let it go and it rises up. As you go higher into the air the air becomes less dense. The balloon will rise until the cool air around it is the same density as the air in the balloon.
Because the gas inside them is less dense than the air around them. When an object is less dense than a fluid (such as air or water) the object will float on the fluid because the buoyant force exerted on the object by the fluid is greater than the force of gravity on the object.
Because hot air rises - therefore the hot air trapped inside of the balloon, that is kept heated hs no where to go - but up.
The volume of the air displaced by the balloon is less than the volume of the 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
How do particles make a hot air balloon work?
Particles in the air are heated by a burner in the hot air balloon, causing them to expand and become less dense. This creates a pressure difference between the inside and outside of the balloon, allowing it to rise and float in the atmosphere.
If you wanted to make a balloon float in the air which gas should you use to fill the balloon?
Helium is commonly used to fill balloons to make them float in the air. Helium is lighter than air, so when it is inside a balloon, it provides buoyancy and causes the balloon to rise.
What happens to volume and mass in a hot air balloon?
In a hot air balloon, the volume of the air inside the balloon increases as the air is heated. This causes the hot air balloon to become less dense than the surrounding air, which allows it to float. The mass of the air inside the balloon remains the same, but its density changes due to the temperature increase.
In a hot air balloon air is heated by a flamehow does this enable the balloon to float in the air?
Heating the air inside the balloon decreases its density, making it lighter than the surrounding air. This causes the balloon to float because it is now less dense and experiences an upward buoyant force. The flame must be constantly heating the air to maintain this temperature difference and keep the balloon aloft.
Why can't a hot air balloon float in outer space?
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.
Why do hot air balloon float?
Hot air balloons float because of a principle known as buoyancy. When the air inside the balloon is heated, it becomes less dense than the surrounding cooler air, causing the balloon to rise. The hot air trapped inside the balloon makes it lighter than the air outside, allowing it to float upwards.
Does a hot air balloon need heat or cold air to float?
hot
What does the hot air balloon have in the middle?
The hot air balloon has a basket in the middle, which holds passengers and the pilot. The basket is attached to the envelope of the balloon, where hot air is used to generate lift and make the balloon float.
How air balloons float?
They are filled with hot air. The hot air raises and take the balloon with it
What makes a hot air balloon float?
A hot air balloon floats because the air inside the balloon is heated, which makes it less dense than the surrounding air. This lower density air creates lift, allowing the balloon to rise. The balloon will continue to float as long as the air inside remains heated.
Why do hot air balloons float in the air?
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.
Why does a balloon need hot air?
A balloon needs hot air to make it rise because hot air is less dense than cold air. When the air inside the balloon is heated, it becomes lighter and causes the balloon to lift off the ground and float in the air.
How does warm air balloons float?
"Warm air", otherwise known as Hot Air Balloons, float because of one basic Law of Thermodynamics; heat rises. The air in a hot air balloon is hot, therefore, the balloon rises.
Why does a hot air balloon float in air?
A hot air balloon floats in the air because the air inside the balloon is heated, becoming less dense than the surrounding air. This creates a buoyant force that lifts the balloon. As long as the air inside the balloon remains hotter than the surrounding air, the balloon will continue to float.
Is a hot air balloon a balanced or unbalanced force?
A hot air balloon is balanced because the upward lift force from the hot air inside the balloon is equal and opposite to the downward force of gravity on the balloon and its contents. This balance allows the hot air balloon to float in the air.
What happens to a hot air balloon that allows it to float through the air?
Air inside the balloon is heated. Hot air is less dense than the surrounding air, and thus the balloon rises.
