What causes a hot air balloon stay afloat?
the buoyancy
Why do hot air balloons rise to a height and stay there?
Hot air balloons rise because the air inside the balloon is heated, making it less dense than the cooler air outside. This difference in density creates buoyancy, allowing the balloon to lift. Once the desired altitude is reached, the pilot can maintain the balloon's height by carefully controlling the temperature of the air inside, either by adding or releasing hot air. As long as the internal air remains warmer than the outside air, the balloon will stay afloat.
Why cant hot-air balloons go to higher layers?
Hot air balloons rely on the temperature difference between the air inside and outside the balloon to generate lift. As you ascend, the temperature of the air outside the balloon decreases, reducing the lift. At higher altitudes, the balloon would need a larger temperature difference to stay afloat, which is difficult to achieve with a burner.
How does a hot air balloon stay up?
A hot air balloon stays up because hot air is less dense than cold air. When the air inside the balloon is heated by the burner, it becomes lighter and causes the balloon to float upwards. By controlling the temperature inside the balloon, the pilot can control the altitude.
Why use heat in a hot air balloon?
Because hot air rises. And I assume because burning fuel to create the hot air is easier, perhaps a lot lighter as well, and definitely cheaper than constantly buying helium. Although blimps used that method.

Can a cocnut stay afloat?
yes,it can stay afloat as it has a waterproof coverings or fibrous husk to trap air.
How does a hot air balloon stays in the air?
A hot air balloon can stay in the air because the hot air is less dense than cool air. The hot air that is blown into the balloon causes it to rise and a burner is used to heat the air inside of the balloon to keep it floating.
Why inflated balloon not sink in water?
An inflated balloon floats in water because the air inside the balloon makes it less dense than water. The buoyant force acting on the balloon is greater than its weight, causing it to float. The air trapped inside the balloon increases its volume and decreases its overall density, allowing it to stay afloat.
Why does a balloon float in the air?
It floats in the air because of the helium inside. Helium's density is less than that of oxygen, same reason fat floats in water.
What makes a helium balloon?
A helium balloon is made by filling a latex or mylar balloon with helium gas, which is lighter than air, causing the balloon to float. The helium gas is sealed inside the balloon, allowing it to stay afloat for a period of time before slowly deflating.
Why cant hot-air balloons go to higher layers?

How would taping a coin to the balloon affect the overall motion of the balloon?
Taping a coin to the balloon would make it heavier, potentially affecting its ability to rise or stay afloat in the air. The added weight may cause the balloon to descend more quickly or limit its upward movement, depending on the size of the coin relative to the balloon.
When a balloon is filled with air is heated does the density of the air in the balloon stay the same?
No it decreases
Why use heat in a hot air balloon?
Because hot air rises. And I assume because burning fuel to create the hot air is easier, perhaps a lot lighter as well, and definitely cheaper than constantly buying helium. Although blimps used that method.
Why is a hellium balloon on the ceiling one day and on the floor the next?
A helium balloon rises to the ceiling because helium is lighter than air, allowing the balloon to float. Over time, helium slowly escapes through the balloon's material, causing it to lose buoyancy. Once the balloon's helium level decreases enough, it can no longer stay afloat and descends to the floor. Temperature changes and air pressure can also affect the balloon's behavior, contributing to its descent.
