How a hot air balloon goes up?
A hot air balloon goes up because the hot air inside is less dense than the surrounding air. Therefore, the hot air rises, bringing the balloon up with it.
How does a hot air balloon gain altitude?
Altitude is controlled by the propane burner and the parachute valve. The parachute valve is an opening at the top of the balloon envelope. When closed, it traps hot air from the burner inside the balloon, making the hot air balloon rise. When opened, it allows hot air to escape, and the hot air balloon descends. The reason a hot air ballon rises is because the density of the balloon is less than the density of the surrounding air. Its the same thing as "why does a boat float". In the case of the balloon, the operator modulates the flame on and off to maintain the desired altitude - increase the flame, and the balloon goes up - decrease or shut off the flame, and the balloon goes down. A better metaphor to a boat is a submarine - add ballast and the submarine goes down - blow ballast and the submarine goes up.
What make a hotair balloon go up?
A hot air balloon goes up because the air inside the balloon is heated, which makes it less dense than the surrounding cooler air. This creates a buoyant force that causes the balloon to rise. The pilot controls the altitude by adjusting the temperature of the air inside the balloon.
Where does air go in a balloon?
When you inflate a balloon, the air goes inside the balloon and fills it up. The air molecules push against the walls of the balloon, causing it to expand and take on its inflated shape.
How much air can a water balloon hold?
The amount of air a water balloon can hold depends on its size and how tightly it is inflated. As the balloon expands with air, the water inside compresses, allowing more air to be added. However, there is a limit to how much air a water balloon can hold before it bursts.
What if the heat source in a hot air balloon goes out?
what goes up, goes down!
What happens to the pressure of the air outside of the balloon as it goes higher?
The pressure of the air outside the balloon decreases as it goes higher in altitude because the air becomes less dense at higher altitudes. This decrease in pressure causes the balloon to expand as the air inside the balloon pushes outward.
How much gas goes into a hot air balloon?
Alot
What if you were to fill a balloon with air then let go of it without tying it closed. What causes the balloon to fly away?
The air pressure inside the balloon is higher than the surrounding air pressure, causing the air to escape rapidly. This creates a force that propels the balloon in the opposite direction, making it fly away.
Why a hot air balloon floats?
A hot air balloon floats because the air inside the balloon is heated, making it less dense than the cooler air outside. This difference in density creates a lifting force called buoyancy, allowing the balloon to rise in the atmosphere.
How does air help a hot air balloon fly?
Well the simple and rather obvious answer is that you need air before you can get hot air. To go a little more complex, when you heat air it becomes less dense and therefore lighter, so it rises. That's why air goes up the chimney. Put the hot air in a balloon, the balloon goes up too...........
What helps a hot air balloon go higher?
A hot air balloon goes higher by increasing the temperature of the air inside the balloon. When the air inside the balloon is heated, it becomes less dense than the surrounding air, allowing the balloon to rise. Pilots can control the altitude by adjusting the heat to maintain the desired height.
