Properties of Matter

Matter Has mass (different than weight which is mass due to gravity) Occupies space

Physical Properties Characteristic Observed or measured Doesn’t change the makeup of the substance Examples: Color, odor, taste, hardness, density, melting point, boiling point

Physical properties of metals Ductile: can be drawn into a wire Malleable: can be hammered into sheets Luster: shine Good conductor of heat and electricity

Density Ratio of mass to volume Density = mass / volume Common units of density: kg/m 3, g/cm 3, g/m. L Practice Problem: A piece of lead has a mass of 22. 7 g. It occupies a volume of 2. 0 cm 3. What is the density of the lead? D= 22. 7/2= 11. 4 g/cm 3

Practice Problem 2 A piece of lead occupies a volume of 4. 0 cm 3. What is the mass of the lead if density is 11. 4 g/cm 3?

Practice Problem 3 A piece of lead (density 11. 4 g/cm 3) has a mass of 302 g. What volume does it occupy?

Chemical Properties that describe how the substance interacts (or fails to interact) with other substances to produce new substances Example: Rust combustion

States of Matter Solid Definite shape and definite volume Liquid Flows, constant volume, and takes the shape of a container Gas Flows to conform to the shape of the container, fills the entire volume of the container
