How does a hot air balloon stay up?
A hot air balloon stays up because hot air is less dense than cold air. When the air inside the balloon is heated by the burner, it becomes lighter and causes the balloon to float upwards. By controlling the temperature inside the balloon, the pilot can control the altitude.
What causes a hot air balloon to stay afloat?
A hot air balloon stays afloat because hot air inside the balloon is less dense than the surrounding cooler air, creating lift. As the air inside the balloon is heated, it expands and becomes lighter, causing the balloon to rise. By controlling the amount of hot air in the balloon, the pilot can control the altitude.
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 does hot air balloon stays up?
The air inside the balloon is heated with a propane burner. As air is warmed, it becomes less dense (lighter) and rises.
How do you keep a balloon up?
A balloon stays up because it is filled with a gas that is lighter than air, such as helium or hot air. This creates a lifting force that counteracts the force of gravity, allowing the balloon to float in the air.
What keeps air balloon inflated?
If you mean a hot air balloon, it is the expansion of the air caused by the propane burner. If you mean any balloon, it is the ability of the material to hold the air or gas inside which keeps it inflated.
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.
What is a hot-air balloon pilot called?
A hot air balloon pilot is called an aeronaut.
Why does balloon fly?
The hot air inside the balloon expands, making the hot air balloon fly.
How do you keep an hot air balloon in the air indefinitely?
To keep a Hot air balloon in the sky indefinitely you must keep all the air sealed and warm. The Hot air's lower density will keep it above the more dense, colder air. To demonstrate this put air inside a bottle and place it on-top of water. Notice how it stays "afloat". ======================================================== To keep a hot air balloon aloft indefinitely, the temperature of the air inside the balloon must be hot enough so that the difference in weight of the air inside the balance and an equivaletnt volume outside of the balloon equals or exceeds the total weight of the balloon and passengers. It doesn have to be air tight. Hot air balloons are open on the bottom. But it has to be air tight enough that the burner will be capable of keeping the air hot enough to maintain altitude.
