you can crumple up the paper
No it doesn't change at all! Crumpling up the paper only changes the shape it but its weight stays the same.
When you crumple a paper you are decreasing the surface area. The less surface area, the less the wind can stop the paper. it also works because you are putting more weight on one area.
you are folding it, there is still only one piece of paper
A phsical change is something that can be changed but cant be changed back. for example: you can crumple a piece of paper but it is still paper. A chemical change means it has been changed perminetly so for example: If you burn the paper its ashes not paper. it was ashes but youy cant change it back into paper. Hope this helps :)

it is a physical change
No, but they are similar. You would crush a can - you would damage it, and compress it. Whereas you would crumple a piece of paper - you would wrinkle it with compression. One is much more violent than the other.
Take a piece of paper and cut it in half (anywhere will do) and you will have two pieces of paper - and your original piece of paper has changed shape.

no, a chemical change is when something turns into something else. as an example burning paper is a chemical reaction because the paper turned into ashes and changed. but if you rip a piece of paper in half its still a piece of paper right. did that answer your question
The plural of a piece of paper is "pieces of paper."
you have to look at the piece of paper and the things that are on the piece of paper follow it
The rusting of an iron pole is a chemical change. An example of a chemical change would be crumbling a piece of paper. When you are crumbling this piece of paper, the contents of the paper have not change and you are able to uncrumble the paper there is no difference except the paper has wrinkles. :) However in an example of chemical change like a metal rusting, you cannot un-rust it, it was chemically changed. Another example of a chemical change would be burning a piece of paper to ashes.
