Physical and Chemical Changes
What is a Physical Change?A physical change alters the form of a substance, but does not change it to another substance. Example: Making Orange Juice
What is a Chemical Change?When a substance undergoes a chemical change, it is changed into a different substance with different properties. Example: Baking a Cake
