Pre-Assessment Properties of Matter

You cannot use extensive properties to tell one substance from another because two very different objects can have the same extensive properties.

Density, boiling point, area and electrical conductivity are properties that can be used to identify an unknown substance.

If you know the intensive property of an unknown substance like density, melting point, boiling point etc., just compare it and you will identify the name of elements you have.

A chemist can make predictions about the type of reactions to expect if they know the properties of a certain substance.

Chemical change must occur for a chemical property to be observed and measured.

Iron and steel have the same magnetic properties. You cannot separate them when place in one container.

Filter paper is used to separate solid particles from a liquid substance.

To identify an unknown substance, you must consider its physical properties.

You can separate rocks from sand by its texture.

Hydrogen peroxide will gradually break down to water and oxygen if it is exposed to light.
