Chemical vs Physical

Physical Properties

Physical Property: HeightThis is a physical property because the people are different heights, but they are still both human beings made up of the same things.

Chemical vs. Physical

Chemical Properties

A physical change is a change of matter from one form to another without a change in chemical properties.

A chemical change is a change that occurs when one or more substances change into entirely new substances with different properties.

Physical Property: ColorThis is a physical property because, although the roses are different colors, they are still made up of the same substances and have the same identity.

Physical Property: ShapeThis is a physical property because, although the leaves are shaped differently, they all have the same molecular makeup.

A chemical reaction is a process that involves rearrangement of the molecular or ionic structure of a substance, as opposed to a change in physical form.

Chemical Property: FlammabilityThis is a chemical property because, as it burns the marshmallow, it changes the molecular makeup of the marshmallow and it cannot be restored back to the original.

Chemical Property: Ability to rustThis is a chemical property because, as iron is exposed to oxygen, the molecular or ionic structure is changed to create rust.

Chemical Property: ToxicitySwordfish contains mercury, which has the property of toxicity. Toxicity is a chemical property because it causes damage to organisms, which changes the molecular makeup of them.

This explosion is a chemical reaction because the combination of the candy and the soda rearranges the molecular or ionic makeup of the original substances and creates a new substance.
