and how can they??

Answer 1

I don't think they can be. A physical change is when something changes, but the chemical make-up of a substance stays the same. Such as melting water. Ice is solid and water is liquid, but they are both H2O. A chemical change is when you have a chemical reaction and the chemical make-up of a substance is changed.  

Answer 2

sorry, this is impossible.
