1. Physical Properties

2. A physical property is a characteristic of matter that you can observe or measure without changing the identity of the matter.

3. Size Dependent Properties Mass is the amount of matter in an object. Weight is the pull of gravity on matter. Weight changes with location (gravity), mass does not. Volume is the amount of space something takes up.

4. Size Independent Properties Melting Point Boiling Point Density: the mass per unit volume of a substance.

5. Size Independent Properties Conductivity: ability to carry electricity Solubility: ability of one substance to dissolve in another

6. Solving for Density Density = Mass Volume
