How does heilum make a balloon float?
When helium is added to a balloon, it decreases the overall density of the balloon compared to the surrounding air. This causes the balloon to float because the buoyant force exerted by the helium is greater than the force of gravity acting on the balloon. This buoyant force allows the balloon to rise in the air.
Why doesnt a balloon float with your air?
A balloon does not float with your breath because the air you blow into it is denser than the surrounding air. To make a balloon float, you need to use a lighter gas, such as helium, which is less dense than the surrounding air and creates enough lift to keep the balloon suspended.
Why does a balloon need hot air?
A balloon needs hot air to make it rise because hot air is less dense than cold air. When the air inside the balloon is heated, it becomes lighter and causes the balloon to lift off the ground and float in the air.
What must happen for a balloon to float in the air?
For a balloon to float in the air, it must be 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.
What gas do you use to make a balloon float?
Helium gas is commonly used to make balloons float because it is lighter than air and creates lift. The helium gas in the balloon is less dense than the surrounding air, causing the balloon to rise.
If you wanted to make a balloon float in the air which gas should you use to fill the balloon?
Helium gas is lighter than air and hence balloons filled with helium will float in air.

How does heating the air inside a hot-air balloon make it to float?
Heating the air inside a hot-air balloon decreases its density, causing it to become lighter than the surrounding cooler air. This buoyant force generated by the temperature difference causes the balloon to float upwards.
Why can't a hot air balloon float in outer space?
A hot air balloon requires air to generate lift. In outer space, there is no air or atmosphere, so there is nothing for the hot air balloon to displace to generate lift, causing it to be unable to float.
What gas does make a balloon float?
Helium gas is commonly used to make balloons float. Helium is lighter than air, so filling a balloon with helium makes it buoyant and able to float.
What does the hot air balloon have in the middle?
The hot air balloon has a basket in the middle, which holds passengers and the pilot. The basket is attached to the envelope of the balloon, where hot air is used to generate lift and make the balloon float.
Why heating the air allows a hot air balloon to float?
Heating the air inside the balloon makes it less dense than the surrounding air, causing the balloon to float. As warm air is lighter than cool air, the balloon rises because of the difference in densities. This creates an upward force, known as buoyancy, that allows the balloon to float.
Does a balloon float or sink on water and why?
A balloon filled with air will float on water because it is less dense than water. The buoyant force acting on the balloon allows it to float.
