Physical Properties

Does it Matter?

Magnetism

• Matter that contains iron or nickel will be attracted to a magnet.

• Not all metals are attracted to a magnet.

Physical State• Three 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 DensitySinking & Floating

• Weight doesn’t determine if an object will sink or float.

• The volume of an object and how much “stuff” (matter) is in the object will determine the density.

Solubility in Water

• Ability of a substance to dissolve when added to water

• A liquid, solid, or gas can be dissolved in water. Examples may include lemon juice in water, sugar in tea, and the carbonation in a soda.

Conduction

• Some materials allow thermal (heat) or electrical energy to flow through them easily.

• These materials are called conductors.

Insulation

• Some materials do not allow thermal (heat) energy or electrical energy to flow through them easily.

• These materials are called insulators.

Does it Matter?

• Matter has properties that can be observed and measured.

• These properties determine how matter is
