Blowing up a balloon is a reversible change because the process can be reversed by letting the air out of the balloon. The balloon returns to its original state before it was blown up.
Yes, blowing up a balloon and letting the air out are physical changes. In both cases, the balloon's shape and size are altered, but its chemical composition remains the same.
Yes, because when it's blown up, it's still gunpowder. Blowing is caused by a chemical reaction.
To blow up a big balloon without a pump, you can simply use your mouth to blow air into the balloon. Hold the neck of the balloon securely while blowing into it to inflate it. It may take a bit more effort and time compared to using a pump, but it is a simple and effective method.
Enzymes are catalysts and increase the speed of a chemical reaction without themselves .A chemical reaction can be represented by a chemical equation. An enzyme is a protein that speeds up a biochemical reaction .
Mixing is a physical process.
Baking soda and vinegar must react. The reaction yields a gas that inflates the balloon.
Blowing up a balloon is not an example of diffusion. Diffusion is the movement of particles from an area of high concentration to an area of low concentration, while blowing up a balloon involves forcing air into the balloon using pressure.
The purpose of blowing up a balloon with a lemon is to demonstrate an alternative method of creating a chemical reaction that produces carbon dioxide gas, which then inflates the balloon. This experiment shows how household items can be used to generate gas through a simple chemical reaction.
Blowing up a balloon is a reversible change because the process can be reversed by letting the air out of the balloon. The balloon returns to its original state before it was blown up.
yes you can
Yes, you can blow up a balloon using a pump or by a chemical reaction that produces gas, such as combining vinegar and baking soda. Alternatively, you can also use a helium tank or a compressed air canister to fill up the balloon.
Put the balloon in the bottle with the blowing up part out and blow it up in the bottle.
it changes form
No, girls cannot blow up a balloon with their nose. Blowing up a balloon requires forceful exhalation from the lungs, which is not possible through the nose.
One way to blow up a balloon without blowing into it is to use a hand pump to inflate the balloon with air. Another method is to use a helium tank and nozzle to fill the balloon with helium gas, which will make it float.
Air pressure is the force responsible for blowing up a balloon. When you blow air into a balloon, the air molecules push against the walls of the balloon, creating pressure inside that causes the balloon to expand.
