Why the rusting of an iron pole is not physical change?
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.

Original Answer:noMore Detailed Answer:For a chemical change to occur, the structure of the paper has to be modifed at the chemical level. Cutting or tearing separates the paper into multiple parts, but each part is still paper.A good example of a chemical change is when the paper is burned. During burning, the paper changes from paper to ash, and the result is a change in the chemical structure.
Does a physical or a chemical change?

It is physical because the appearance hasn't changed at all and is the same paper still. For example, if you burned the paper that would be a chemical change because the paper turned into ash and is releasing gas which is a resulting chemical change that has just happened. Hope this helped :) -V
