In a nutshell, air rises and expands when heated. Through the use of a burner the balloon pilot heats up the air inside the envelope (the balloon itself), this air inside the envelope expands and rises, lifing the basket.

How a hot air balloon is lifted from the ground?

A hot air balloon is lifted from the ground by heating the air inside the balloon with a burner. As the air inside the balloon heats up, it becomes less dense than the surrounding air, causing the balloon to rise. The pilot can control the ascent and descent of the balloon by adjusting the temperature of the air inside.


How does a hot air balloon rise in the sky?

A hot air balloon rises in the sky because the air inside the balloon is heated, making it less dense than the surrounding air. This causes the balloon to float upwards, as the less dense hot air inside the balloon is lifted by the denser, cooler air outside.


Does a hot air-balloon have gravatitional energy?

Yes as it uses thermol energy to keep it up, it also uses the gravitional one too


What forces on hot air balloon?

A hot air balloon is lifted by the force of buoyancy, which is created when the hot air inside the balloon is lighter than the cooler air outside. The balloon is also affected by wind currents, which can push it in different directions. Additionally, the burners used to heat the air in the balloon generate thrust to control the altitude and direction of the balloon.


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.


What could a pilot do cause the balloon back to the ground?

If a hot air balloon, then stop heating the air. If a lighter-than-air balloon then release some of the gas.


How does a hot air balloon lift of the ground?

A hot air balloon lifts off the ground by heating the air inside the balloon using a propane burner. As the air inside the balloon heats up, it becomes less dense and expands, creating lift. The hot air inside the balloon is lighter than the cooler air outside, causing the balloon to rise.


How do you get off a hot air balloon?

You climb out when the balloon lands on the ground and the basket is secure.


Why does a hot air balloon get off the ground?

A hot air balloon rises because the air inside the balloon is heated, making it less dense than the surrounding cooler air. This temperature difference creates a buoyant force that lifts the balloon off the ground.


What type of energy is a balloon floating?

A balloon floating in the air is using potential energy, which is energy stored in an object due to its position. The balloon is being lifted by buoyant force, which is the result of the difference in densities between the helium inside the balloon and the air outside.


Why does the hot air balloon come down?

Once the air cools, the balloon will lose its lift and settle back to the ground.


In a hot air balloon air is heated by a flame Explain how this enables the balloon to float?

Heating the air inside the balloon makes it less dense than the surrounding air, causing the balloon to float upwards. As the air inside the balloon cools, it becomes denser and the balloon descends. The pilot can control the altitude by adjusting the temperature of the air inside the balloon.
