Is a hot-air balloon buoyant?
Yes, hot air balloons are less dense and therefore buoyant ============================================ Hot air balloons are buoyant to the extent that the weight of the hot air in the balloon is lighter than the free air. When the difference is more than the weight of the balloon and its contents it will be buoyant and will ascend.
Why hot air balloons rises up in the sky?
Hot air has density less than the air surrounding the balloon. When the average density of the balloon filled with hot air is less than the density of the air outside upthrust is more than the weight of the balloon. therefore it keeps on rising up till the upthrust becomes equal to the weight of the balloon.
How much weight can an hot air balloon hold?
3 pounds
How do you guide the hot air balloon?
You change the volume or the weight of the balloon to raise it or lower it into air currents that are traveling where you want to go.
Why does a hot air balloon fly?
A hot air balloon flies because it is filled with hot air. Hot air rises and causes the balloon to lift from the ground.
What would happen if a hot air balloon's envelope was not balanced in weight?
The Hot air balloon wouldnt fly strait

How much weight can a hot air balloon hold?
It depends on the size and how hot the air inside is
How does a hot-air balloon rise?
The upthrust on the balloon is greater than the weight of the balloon. Thus, it rises upwards. The upthrust on the balloon is greater than the weight of the balloon because the air inside it has a lower density than the surrounding air.

How does a hot air balloon float even though it is so heavy?
Well the basic answer is that when the balloon is 'floating' it is not heavy. The hot air inside the balloon is less dense and therefore lighter than the ambient air. The hotter it is, the lighter it is. When the weight loss of the air inside the balloon is equivalent to the weight of the balloon and equipment, passengers, etc., then it will float. The weight reduction of heated air is quite small which is why balloons have to be so big.
Why does a balloon containing hot air rise while one containing cold air falls?
Because hot air is less dense (ie lighter) than cooler air, it rises. If the total weight of the balloon,( including the warmer air inside it) weighs less than the exact volume of the cooler air which it displaces, it will 'float' upwards. When the air inside cools to a point where the total weight of the balloon equals the weight of the volume of air it displaces, it will cease to rise.... it will 'hover'. If the hot air further cools to where the total balloon weight is greater than that of the displaced air, the balloon will descend.

What should a hot air balloonist do to go higher?
They can drop weight over the side, increase the hot air volume, or both. A hot air balloon will rise when its buoyancy exceeds its weight. So the balloonist can increase the buoyancy by increasing the amount of hot air contained in the balloon. Or they can simply reduce the weight of the balloon, including the gondola, its contents, and contained hot air.
How do you keep an hot air balloon in the air indefinitely?
To keep a Hot air balloon in the sky indefinitely you must keep all the air sealed and warm. The Hot air's lower density will keep it above the more dense, colder air. To demonstrate this put air inside a bottle and place it on-top of water. Notice how it stays "afloat". ======================================================== To keep a hot air balloon aloft indefinitely, the temperature of the air inside the balloon must be hot enough so that the difference in weight of the air inside the balance and an equivaletnt volume outside of the balloon equals or exceeds the total weight of the balloon and passengers. It doesn have to be air tight. Hot air balloons are open on the bottom. But it has to be air tight enough that the burner will be capable of keeping the air hot enough to maintain altitude.
