Physical & Chemical

By: Jacob Klassen 4th Period

Physical Properties

The definition is: characteristics that describe an object.

Some examples are: the density of an object, the volume of an object, and the mass of an object.

Something that you might get confused by is wood turning into ash but that is not a physical property.

Chemical Properties

The definition is a characteristic that is observed when a substance interacts with another substance.

Some examples would be wood is flammable, silver can tarnish, and metal can rust.

You might get wood burning confused with a chemical property but that is not a chemical property.

Physical Change

The definition is matter has changed state but remains the same.

Three examples are:ice turning to water, water turning to ice, and water becoming steam.

Wood burning and turning into ash is NOT a physical change.

Chemical Change

The definition is a process that changes substances into new substances.

Some examples are wood becoming ash, metal rusting and a match turning into smoke,fire,heat etc.

When you add salt to water that isn't a chemical change.

The 5 indicators for chemical change are the color changes, odor is released, a new substance is formed, gas is produced and the temperature changes.
