Physical Versus Chemical Properties in Matter

The video explains the difference between physical and chemical properties. Physical properties, such as boiling and melting points, do not change the chemical identity of a substance. Chemical properties, like flammability and corrosiveness, involve a change in chemical identity. The video provides examples and comparisons to clarify these concepts.

What is a characteristic of a physical property?

• It always involves a change in color.

• It does not change the chemical identity of a substance.

• It involves a chemical reaction.
