Physical and Chemical Changes
(b) Crushing a can : after crushing can changes its shape, size but it still remain Aluminum so it is a physical change. Burning of wood is a chemical change because on burning wood changes to a totally different new products (ash, smoke and carbon dioxide). Here is video of a lab with a number of examples of both chemical and physical changes.
