Physical Properties Does it Matter?

Magnetism Matter that contains iron, iron alloys, or nickel will be attracted to a magnet Not all metals are attracted to a magnet

Physical State Physical State 3 forms: liquid, solid, or gas Can change from one form to another by the processes of melting, freezing, evaporation, and condensation Temperature changes are involved with changes in state

Mass Mass is the amount of matter in an object. Mass is measured with a balance. Mass is not the same as weight. Weight is a result of the pull of gravity on an object and is measured with a scale.

Relative Density Sinking & Floating Weight doesn’t determine if an object will sink or float. How much space an object takes up and how much matter the object contains determines density.

Solubility in Water Ability of a substance to dissolve when added to water A liquid (ie: lemon juice), a solid (ie: powdered drink mix), or a gas (ie: carbon dioxide) can be dissolved in water.

Conduction Some materials allow thermal (heat) energy or electrical energy to flow through them easily. Such materials are called conductors.

Insulation Some materials do not allow thermal (heat) energy or electrical energy to flow through them easily. Such materials are called insulators.
