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.
What else can I help you with?
Why doesnt waterfilled balloon burst when heated?
You can have the candle flame actually touch the balloon, and the balloon won't break! The water in the balloon is absorbing the heat from the candle. The balloon conducts heat very well, so the candle flame transfers to the water without harming the balloon.
Can you hold a balloon under a flame without popping it?
No, holding a balloon under a flame will cause it to pop because the heat weakens the rubber material, leading to a sudden burst. It's not advisable to expose a balloon to direct flame or heat sources.
Why does balloon filled with water do not blast when it is shown to fire?
Why does the balloon with no water break in the flame? And balloon with water not break? The flame heats the rubber of both balloons. The rubber of the balloon without water becomes so hot, that it becomes too weak to resist the pressure of the air inside the balloon. When water inside the balloon is placed in the flame, the water absorbs most of the heat from the flame. Then, the rubber of the balloon does not become very hot. Because the rubber does not become hot, it does not weaken, and the balloon does not break. Water is a good absorber of heat
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.
Why does a balloon pop over a candle?
When a balloon is held over a flame, the heat causes the air inside to expand rapidly. This increase in pressure can exceed the strength of the balloon material, causing it to burst. Additionally, the heat from the flame weakens the elasticity of the balloon, making it more prone to popping.
Inflate a balloon and tie it closed hold it over the flame observe what happens?
Heating a balloon can cause it to expand due to the increase in temperature. If the balloon is not made of flame-resistant material, it is likely to burst when exposed to the flame due to the buildup of pressure from the expanding air inside. This experiment can be dangerous and may result in the balloon popping and potential injury, so caution should be exercised.
Is an air inside a balloon a pure substance?
The air inside a hot air balloon is the same as normal air around the balloon and the air you're breathing, only heated by the flame inside the balloon, hence HOT AIR balloon.
How is a hot air balloon able to float with a flame?
As to the reason a hot air balloon floats has already been explained, I will answer your question regarding the flame. The gas burner provides the flame which is placed just in the mouth of the ballon, when lit it provides more heat to the cooling air in the balloon causing the balloon to maintain altitude.
What kind of gas is used for air balloon?
Just plain old ordinary air, but heated by the flame of the burner (which I believe burns propane gas).
How does a candle powered hot air balloon work?
A candle-powered hot air balloon works by heating the air inside the balloon with a suspended candle flame. As the air inside the balloon is heated, it becomes less dense and rises, creating lift. The balloon will continue to rise until the air inside cools down or the flame is extinguished.
What element gives a green flame when it is heated?
Boron is the element that gives a green flame when it is heated.
Why doesnt waterfilled balloon burst when heated?
You can have the candle flame actually touch the balloon, and the balloon won't break! The water in the balloon is absorbing the heat from the candle. The balloon conducts heat very well, so the candle flame transfers to the water without harming the balloon.
Can you hold a balloon under a flame without popping it?
No, holding a balloon under a flame will cause it to pop because the heat weakens the rubber material, leading to a sudden burst. It's not advisable to expose a balloon to direct flame or heat sources.
Why does a balloon filled with air and no water pop when placed over a flame?
If a balloon is filled with water, it becomes less susceptible to being popped over a flame, because the water can absorb some of the heat. Otherwise, the flame will rapidly destroy the material of the balloon (rubber, latex).
Why does a hot air balloon need flame in order to take off?
A hot air balloon needs a flame to heat the air inside the balloon, making it less dense than the surrounding air. This temperature difference creates lift, allowing the balloon to float upwards. Without the flame, the air inside the balloon would cool down and the balloon would descend.
How do hot air balloons trap air inside?
Hot air balloons work by heating the air inside the balloon envelope using a propane burner. When the air inside the balloon is heated, it becomes lighter and less dense than the surrounding air, causing the balloon to rise. The envelope of the balloon is sealed, which allows the hot air to be trapped inside and keep the balloon aloft.
What is the thing coled on a hot air balloon that puts a flame up in to the balloon?
The piece of equipment that put the flame up into the balloon is called the 'burner' in most parts of the world. It is also sometimes called a 'heater'.
