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.

Yes. Oxygen combines with the metal to form an oxide.
Is electroplating a chemical or physical change?
Electroplating is a chemical change. Solutions containing metal ions are placed in a tank, and the piece of metal to be plated is connected to the electrical supply to become the cathode. The metal ions in solution are attracted to the cathode where they are reduced (reduction is gain of electrons) to form a metal coating.
