Physical vs. Chemical
A physical property is a characteristic of something that can be observed without changing the substance or thing into something else.
A characteristic that is observed when a substance interacts with another substance. My own personal defenition is: Something you see when a chemicals reacts.
A change in matter that does not affect its chemical composition. When something changes it's apperance but not it's chemical.
A chemical reaction; a process that changes substances into a new one. In other words it is when a chemical changes it's substances.
