Examples of chemical changes would be burning, cooking, rusting, and rotting. Examples of physical changes could be boiling, melting, freezing, and shredding.
A new compound (product) results from a chemical change as the atoms rearrange themselves to form new chemical bonds. A chemical change always involves a chemical reaction. The starting materials and final product are chemically different from one another. Here are some examples of chemical changes:
Burning wood
Souring milk
Mixing acid and base
Digesting food
Cooking an egg
Heating sugar to form caramel
Baking a cake
Rusting of iron
Examples of Physical Changes
No new chemical species forms in a physical change. Changing the state of a pure substance between solid, liquid, or gas phase is a physical changes since the identity of the matter does not change. A physical change involves changes in physical properties, but not chemical properties. For example, physical properties change during tempering steel, crystallization, and melting. Here are examples of physical changes:
