In relation to the small balloons children are so fond a carrying, the balloon is lifted because it is filled with a lighter than air gas(helium/hydrogen). it falls when this gas leaks out over time.
In relation to hot air balloons, the air is heated in the balloon causing it to rise(because hot air is less dense than warm). Over time the air cools and so the balloon falls. You can also expedite the rising of the balloon by jettisoning many of the weights that line the balloon.

What makes balloons float when they are full of air but not float when they are deflated?
Balloons float when they are full of air because the helium or air inside is less dense than the surrounding air, creating buoyancy. When they are deflated, the balloon is denser than the surrounding air, causing it to sink rather than float. This is due to the principle of buoyancy and the difference in density between the balloon and the air.
Why do balloons float in the air?
Balloons float in the air because they are filled with a gas that is lighter than the surrounding air, such as helium or hot air. This creates a buoyant force that allows the balloon to rise and float.
How do helium balloons float in the air?
Helium balloons float in the air because helium is lighter than the surrounding air. This causes the balloon to be buoyant and rise upwards.
How do balloons float in the air?
Balloons float in the air because they are filled with a gas that is lighter than the surrounding air. This gas, typically helium or hydrogen, creates buoyancy, causing the balloon to rise and float.
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.

Where in the atmosphere do hot air balloons float?
Hot air balloons float because hot air displaces cool air in the atmosphere
Why don't sulfur hexafluoride balloons float?
The air is too strong, which makes the balloon sink, along with the weight of the balloon's material.
Why do balloons float in the air?
Balloons float in the air because they are filled with a gas that is lighter than the surrounding air, such as helium or hot air. This creates a buoyant force that allows the balloon to rise and float.
Does styrofoam sink in air or float?
sink
Will the helium football be light then a aired football?
yes. think about balloons: a ballon with helium will float while a balloon with good ol' air will sink
Why do helium balloons float better than just air balloons?
helium is less dense than air. :) so helium will float better than air
How do helium balloons float in the air?
Helium balloons float in the air because helium is lighter than the surrounding air. This causes the balloon to be buoyant and rise upwards.
How do balloons float in the air?
Balloons float in the air because they are filled with a gas that is lighter than the surrounding air. This gas, typically helium or hydrogen, creates buoyancy, causing the balloon to rise and float.
Will warming helium balloons make them float?
Helium is lighter than air. so balloons filled with helium will float in air. warming will make them float or rise up faster.
If you trap air in a balloon and put it into warm air will it float?
If the air in the balloon is cooler than the air around it, it will sink. Hot air balloons go up because they weigh less than the air around them.
Why do balloons only float with helium?
Balloons filled with helium float because helium is lighter than the surrounding air, creating a lifting force. This is known as buoyancy. Regular air-filled balloons are denser than the surrounding air and do not float.
