The Physical Properties of Matter

What is a physical property of matter? A property that can be observed or measured without changing the identity of that matter Ex: Color, odor, shape, size, etc.

Classifying matter Matter can be classified, or put into the following groups: Mass Volume Temperature Relative Density Physical state Solubility Magnetism Thermal/Electrical conductors

Temperature Definition: The measure of energy of motion of the particles in matter. Temperature can be measured by using a thermometer. Scientists always use celsius.

Volume Definition: The amount of space something takes up. When air is blown into a balloon you can see that it has volume. Volume can be measured by using a graduated cylinder.

Mass` Definition: Mass is the amount of matter in something. A bowling ball and a basketball have about the same volume, but the bowling ball has greater mass because it has more matter. Mass can be measured using a balance.

Relative Density Definition: Density determines whether on substance will sink or float in another. Oil is less dense than water, which is why it floats above water.

State Definition: Example: Ice = Solid Water = Liquid Helium = Gas The physical state of matter, which are solids, liquids, and gases. Example: Ice = Solid Water = Liquid Helium = Gas

Solubility Definition: The ability for one substance to dissolve into another substance Example: Sugar dissolves when making lemonade.

Magnetism Definition: The pulling force of a magnet. Substances such as iron and a few other metals are attracted to magnets. A magnet has no effect on non magnetic substances, such as paper, wood, or glass.

Thermal/Electrical conductors A conductor is a material that easily transfers heat or electricity. Metals are good conductors for thermal energy. Substances such as plastic or wooden spoons are not. Metals are a good conductor of electricity.
