Physical Property: A physical property is one that is displayed without any change in composition. (Intensive or Extensive)
Physical Change: Change in which the matter's physical appearance is altered, but composition remains unchanged. (Change in state of matter)
Chemical Property: Any characteristic that gives a sample of matter the ability/inability to undergo a change that alters its composition. Examples: Alkali metals react with water; Paper's ability to burn.
Chemical Change: Change in which one or more kinds of matter are transformed to new kinds of matter with altered compositions (or Chemical Reaction).
Think physical, you can change your physical appearance, meaning, you can change a person from being fat to skinny. That's a physical change. You're the same person, just thinner. Nothing about you has changed chemically. You're not a rock or a plant, still a human being.
an example of a chemical change is baking a cake. You start with powder and some milk, and that milk combines with the powder to form a "solid".
If it were to remain as milk and powder, it would NOT be a chemical change.
anytime you form something completely NEW than what you started with is a chemical change.
