What does the balloon experiment show?

In the balloon balance experiment, we are blowing up balloons. When blow-up balloons, the air is entering inside them and making the balloons expand. So, this shows that the air occupies space which eventually proves that it has weight.

What is the science behind a self inflating balloon?

When an acid is mixed with a base, the two mixtures react through an endothermic reaction (a reaction that makes the mixture feel colder), creating CO2 gas which bubbles up through the liquid and out into the air, which inflates the balloon.

What made the balloons Magic Balloons?

This is because during the whole process, a gas is produced in the form of carbon dioxide. Since the balloon restricts the release of this gas, it is then trapped inside the bottle. Its build up inside the bottle causes it to fill the balloon and eventually inflate it! Now you have just created a magic balloon!

Why did the balloon expand more in the presence of sugar than without it?

Why? As the yeast continued to react, it converted more and more sugar into carbon dioxide gas. This gas was trapped in the balloon, making it inflate as if by magic! It took about an hour for our balloon to reach its maximum size.

What did you observe after releasing the air from the balloon?

When you release the opening of the balloon, gas quickly escapes to equalize the pressure inside with the air pressure outside of the balloon. As the gases escape from the balloon, the gas particles exert a force on the ground and the air outside of the balloon.

What caused the change in the balloon?

Air molecules collide into the balloon with the same energy inside and outside the balloon. When the bottle is heated, the air molecules inside start moving faster. These molecules now collide into the balloon with more energy resulting in increased pressure. The increased pressure causes the balloon to expand.

Is inflating a balloon a chemical or physical change?

blowing a balloon is a physical change as when you blow a balloon the balloon expands but the balloon remains a balloon . there is change in size but the material is same .

What type of change inflating of a balloon is?

Inflating a balloon is a reversible change. When air is blown into a balloon, its shape and size change and the balloon gets inflated. Now when the air filled in the balloon is allowed to escape, the balloon comes back to its original size and shape. Hence, inflating a balloon is a reversible change.

How do you inflate a balloon without air?

Put 10g of baking soda inside the balloon using a funnel. Stretch the mouth of the balloon over the top of the bottle (without spilling the contents) and use a rubber band to tie it around the bottle neck. Pour the contents of the balloon inside the bottle. The balloon will slowly be inflated.

Does the amount of sugar affect the size of the balloon?

If the size of the balloon depends on the amount of sugar added, then the more sugar added will increase the size of the balloon because of the occurrence of cellular respiration. The balloon will become bigger from Carbon dioxide being produced.

Why do balloons inflate with yeast and sugar?

As the yeast feeds on the sugar, it produces carbon dioxide. With no place to go but up, this gas slowly fills the balloon. A very similar process happens as bread rises. Carbon dioxide from yeast fills thousands of balloonlike bubbles in the dough.
