yes it is reversible
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.
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.
Yes, because when it's blown up, it's still gunpowder. Blowing is caused by a chemical reaction.
you get a pin and jab itWhat you need to do is get a bottle and fill it with sugar and yeast and warm water. then let it stay like that for 2 to 3 hours. Or you could just blow it up using your mouth- much simpler! Or use a ballon pump
If you blow it up with your mouth you make it heavier. You breathe out air containing a higher proportion of carbon dioxide than the air you breathe in. Carbon dioxide is a relatively heavy gas (nearly three times as dense as air) and so this increased amount of gas, plus the rest of the air in the balloon, will make the balloon heavier.
it changes form
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.
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 you can
Put the balloon in the bottle with the blowing up part out and blow it up in the bottle.
Blowing up a balloon is a physical change because the air being blown into the balloon does not alter the chemical composition of the balloon material. The change is reversible, as the balloon can be deflated and reinflated multiple times without changing its chemical makeup.
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.
Assuming you meant expanding, which means growing larger. Blowing up a balloon, for instance, causes the balloon to expand.
your get someone whipped cream and mix it in with water and before blowing the balloon up you have to but the whit water in.
Blowing up a balloon with a helium tank, then blowing up a different balloon with your mouth will make a difference in the outcome of your experiment. It'll most likely give you more sources of error.
