Why hot air balloons are made of nylons?
well, hot air balloons are made from nylons because so it does not burn or catch on fire with the flames
Why can hot air balloons only go so high?
air density and temperature
Why did the montgolfer brothers invent the hot air balloon?
Because their life ambition was to learn how to fly 'like birds' and the hot air balloon was their discovery. It was based on the theory that hot air rises. This is why hot air balloons are so big because just to lift a small amount of weight there has to be a lot of air.
Is it true that hot air balloons were flown before hydrogen balloons were flown?
Yes, hot air balloons flew first. Though I don't know the exact details, as the history is so diverse, spread over many years, and even includes the candle lit paper hot air balloons released at parties or festivals. It would take some research on the internet to get the full details.
Why are hot air balloons circular?
Circles and spheres have the least amount of surface area per volume than any other shape, and so it is a very popular shape for hot-air balloons as less heat is dissipated through the skin of the balloon.That being said, hot-air balloons have been made in many different shapes.
Do you like hot air balloons?
oh yeah! they are so cool! big balloons... fun.. no actually, it sucks

What is added to balloons and hot air balloons?
Balloons can be filled with air (don't float), or with hydrogen or helium (float because the gas is less dense). Hot air balloons use burners to heat the air so that it becomes slightly less dense than the cooler air around it, providing some lift.
Why does the temperature near the ceiling tend to be warmer than near the floor?
Hot air rises cold air falls, a example of this is hot-air balloons, hot-air balloons use a fire to heat up the air inside it so it will rise and they also have a latch to relase some of the hot air so that the ballon will desend.
What element is used inside balloons so it will float?
Helium is the gas usually used now. Hydrogen works, but is inflammable and so dangerous. There are also hot air balloons which require a heater to create the hot air and keep it hot.

Is buoyant force exerted by air also?
Yes, that is what makes hot air balloons and helium balloons float. Since air is far less dense than water, you need to displace far more air to get an object that floats on water to float in air. That's why hot air balloons are so huge.
How do hot-air balloons achieve liftoff?
They achieve liftoff by filling up the envelope with hot air, hot air is less dense and so it rises. To lower the hot air balloon, they will pull a string to release the hot air.
Do hot air balloons pollute?
Hot air balloons burn fossil fuels to produce the heat they need to fly. Anything which burns fuel must also release some pollutants. So yes, hot air balloons do pollute. But it should be noted that most burn propane which is a very clean fuel.
how are hot air balloons different then planes in lift?
The hot air inside the balloon is less dense than the cold air outside, so the balloon floats on the denser air. But an airplane relies on a wing moving through the air to create lower pressure on the top of the wing, so that air below pushes the wing up. hot air balloons require no movement.
Is it true that hot air balloons were flown before hydrogen balloons were flown?
Yes, hot air balloons flew first. Though I don't know the exact details, as the history is so diverse, spread over many years, and even includes the candle lit paper hot air balloons released at parties or festivals. It would take some research on the internet to get the full details.
