The balloon skin must hold sufficient volume of lighter, hot air in order to pull the associated weight of the skin itself, the onboard gas cylinders and heating apparatus, any ropes which are needed to hold a dangling basket, the basket, counter-weights, passengers, supplies, and any other items of any weight up through the denser cold air outside it.
Heat makes for less dense molecule compaction because those molecules are moving in relation to the charge of energy they are holding. Less dense molecules rise above the more dense molecules which surround them. The pull of gravity on the ensemble must be overcome, so there must be sufficient volume within. Thus, a bigger balloon can lift more weight.

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 are hot air balloons so big?
because they just are
Why can hot air balloons only go so high?
air density and temperature
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.

What are the disadvantages of hot air balloons?
Hot air balloons have no forward propulsion or steering mechanism. The pilot only has control over the vertical travel of the aircraft. In order to achieve travel in any given direction, the pilot must find an altitude in which the wind is blowing the desired direction. There is a large amount of luck involved in navigating a hot air balloon. Hot air balloons can be extremely difficult to launch and/or land, and doing so safely requires a large team of personnel.
Why can hot air balloons only go so high?
air density and temperature
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.
Do you like hot air balloons?
oh yeah! they are so cool! big balloons... fun.. no actually, it sucks
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.
Why can't a hot air balloon fly straight up when taking off?
Because the balloons are so large even a light breeze will blow them sideways.
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.
