Hot air balloons get their buoyancy from hot air created by a propane burner at the base of the balloon. Hot air is less dense than cold air and so weighs less. When the cold air that is displaced weighs more than the balloon, the balloon will rise. The balloons weight is controlled by turning the burner on and off when needed. The hot air is less dense than the outside air and so the balloon is
squeezed upwards by the surrounding air. The air becomes less dense as more heat is applied, particles separate more and more when heat is applied. The more heat is applied the further apart and less dense the particles become.
A hot air balloon works on the principle that hot air is lighter than cold air, causing it to rise. The burner heats the air inside the balloon envelope, making it less dense and creating lift. By controlling the temperature of the air inside the balloon, the pilot can ascend or descend as needed.

How does Archimedes principal work in hot air balloon?
Archimedes' principle states that the buoyant force on an object is equal to the weight of the fluid displaced by the object. In a hot air balloon, the heated air inside the balloon is less dense than the cooler air outside, creating a buoyant force that lifts the balloon. This principle allows the hot air balloon to float in the air by displacing enough air to lift its weight.
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 kind of energy does a hot air balloon have?
The hot air has thermal energy, and when the balloon is up in the air, it also has gravitational potential energy.
Why doesn't the hot air escape out of the bottom of a hot air balloon?
The hot air inside a hot air balloon is less dense than the cooler air outside, causing it to float upwards instead of escaping out of the bottom. The fabric of the balloon acts as a barrier, trapping the hot air inside the balloon.
How does convection work in a hot air balloon?
In a hot air balloon, the burner heats the air inside the balloon envelope, causing it to become less dense than the surrounding air. This creates a pressure difference, with the warmer air rising above the cooler air, thus generating upward convection currents that lift the balloon. By controlling the temperature of the air inside the envelope, the pilot can control the altitude of the balloon.
Why do hot air balloons work?
Hot air balloons work by heating the air inside the balloon with a burner, which makes the air less dense and causes the balloon to rise. This is because the hot air inside the balloon is lighter than the cooler air outside, creating a buoyant force that lifts the balloon. By controlling the temperature of the air inside the balloon, the pilot can control the altitude of the balloon.
How do the vents work on a hot air balloon?
the vents work because of the heat which can make the hot air balloon go up
How do vents work on a hot air balloon?
the vents work because of the heat which can make the hot air balloon go up
What are reasons why a hot air balloon won't work?
They do work.
What happens to hotair balloon on the moon?
A hot air balloon would not work on the moon.
How does hot air balloon work?
the balloon works with the poplo force forcing it up
Does a hot air balloon need CO2 to lift?
No, a hot air balloon does not need CO2 to lift. Hot air balloons work on the principle that hot air is less dense than cooler air, causing it to rise. When the air inside the balloon is heated, it becomes lighter than the surrounding air, allowing the balloon to lift off the ground.
How did the first hot air balloon work?
The first hot air balloon, created by the Montgolfier brothers in 1783, worked by heating air inside a silk and paper envelope. When the air inside the balloon was heated, it became less dense than the surrounding air, causing the balloon to rise. This principle, known as hot air or thermal buoyancy, allowed the balloon to float in the sky.
How is a hot balloon lifted into the air?
to make a hot air balloon rise you use hot air
Why does a hot balloon fly?
A hot air balloon flies because it is filled with hot air. Hot air rises and causes the balloon to lift from the ground.
Why does a hot air balloon fly?
A hot air balloon flies because hot air inside the balloon is less dense than the cooler air outside. This temperature difference creates lift, allowing the balloon to rise and float in the air. By controlling the temperature of the air inside the balloon, the pilot can control the balloon's ascent and descent.
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.
