ringing a bell a chemical changes
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.
Upon your tongue's contact with the ice pop, the saliva on your tongue freezes, thus giving the effect that your tongue sticks to the ice pop. The same effect can be achieved by dipping your finger in water, then touching it to the ice pop.
Ice cubes will float longer in flat pop compared to carbonated pop. Carbonation creates bubbles, which attach to the surface of the ice cube and cause it to rise to the top more quickly. With flat pop, there are fewer bubbles to lift the ice cube, so it will remain submerged for a longer period.
It probably could be, but it depends on the pop. I think it depends on what it has in it.
Chemical
Pop cans are produced by physical processes.
is a physical change. The popsicle is still a popsicle even if its freezed, nothing has changed with it but its physical appearance :)

the chemicals in the soda interact with the pop rocks and they some times blow up.

Mixing is a physical process.
Becasue of chemical chain reactions.
Physical. As water enters the cracks and crevices and subsequently freezes due to low temperatures it expands and splits the rock. Sometimes you can actually hear that happen in desert canyons or playas; it makes a loud pop.
When mentos touches the pop, it forms bubbles on the mentos, eating away the coating and the carbon dioxide mixes with it making fizz as it breaks it down.
Crushing an aluminum can is a physical change because you have only changed its shape, but not its chemical composition.
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.
