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.
Hot air balloons are large to provide enough lift to carry the weight of the basket, passengers, and fuel. The volume of hot air inside the balloon determines its lifting power, so the larger the balloon, the more hot air it can hold and the more weight it can lift. Additionally, the size helps make the balloon more visible and stable in the air.

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?
Hot air balloons need to be large in order to generate enough lift to carry their payload. The volume of hot air inside the balloon determines its buoyancy, so a larger balloon can hold more hot air and lift more weight. Additionally, the size of the balloon helps create a stable and controlled flight path.
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?
Hot air balloons are circular because the round shape evenly distributes the pressure of the hot air inside, which helps the balloon to maintain its stability and structural integrity while in the air. The circular shape also allows for easy control and maneuverability during flight.
What gas do we fill in hot air balloon?
Hot air balloons are filled with hot air from a propane burner in the basket. Hot air rises. So provided the cooling air in the balloon is topped up from short blasts from the burner, the balloon will rise off the ground.

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 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.
What are the disadvantages of hot air balloons?
Some disadvantages of hot air balloons include their dependence on weather conditions for safe operation, limited control over direction and landing spots, and limited capacity for passengers and cargo. Additionally, they require large open spaces for takeoff and landing, which can be challenging in certain environments.
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.
What element is used inside balloons so it will float?
Helium gas is used inside balloons to make them float. Helium is lighter than air, so it creates a buoyant force that causes the balloon to rise in the atmosphere.
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 couldn't a hot air balloon continue into the air and leave the Earth's atmosphere?
a hot air balloon only works using thermals, which are currents of hot air rising because one area is heated more than the others. so hot air balloons depend on air to keep it airborne, specifically hot air. once it leaves the earths atmosphere, it is a vacuum. there is no air, so the hot air balloon will fall back into the earth. hence, we see that hot air balloons cannot leave the earth's atmosphere.
