Crushing an aluminum can is a physical change because you have only changed its shape, but not its chemical composition.
Yes. Crushing an aluminum can is a physical change because crushing changes only its shape, but not its chemical composition.

Crushing doesn't change the chemical composition of the substance.
because... i don't know :(
This is a physical change.
is a physical change. The popsicle is still a popsicle even if its freezed, nothing has changed with it but its physical appearance :)
Both. The chemical change is H2CO3 decomposing into H2O and CO2. The physical change is the dissolved CO2 forming a bubble and "fizzing" up to the surface.
Its a chemical change because a gas is produced (which is one of the signs of chemical reaction)
When thinking of a balloon, it's best to think of two different chemical compounds that do not mix, the balloon itself and air. What makes the balloon pop is that the pressure of the air exceeds the force of the chemical bonds of the balloon. In order for a chemical reaction to take place, you need to start off with one set of chemicals that become a new set of chemicals.However, when a balloon pops, no new chemicals are created. All that happens is that the electron bonds of the compound we know of as the balloon break.
It IS chemical, but it's not a heat reaction. It's respiration. Yeast is a living organism, which consumes sugar and excretes CO2 and alcohol. - - - - - chemical, because its reacting with heat & that always means chemical. it just includes a physical change..
Pop cans are produced by physical processes.
yes it is
Drinking pop can change your PH scale if you drink a lot of it

The pop that results is caused by the release of carbon dioxide bubbles that are encapsulated within the candy. This is a physical change, rather than a chemical reaction, because no new products are formed.
i think its chemical. Because the only thing physical that's related is opening the pop.

Pop Rising throws right.
Scoliosis
Yes because it doesnt pop it just starts to lose air the more you use it
No. its a chemical change.Once its popped, you cant change it back.
