1. Intensive and Extensive Properties

2. Extensive Properties that do depend on the amount of matter present.
Mass, weight, volume, length

3. Intensive
Properties that do not depend on the amount of the matter present.
Color , odor, hardness, melting/freezing point, boiling point, density, malleability, luster

4. Density Density = mass (g) volume (mL)
Volume can either be determined by the water displacement method or V = L x W x H (units will be cubic centimeters cm3)
Example: Calculate the density in g/mL of aluminum if a 50 mL block weighs 135 g
Solution: Apply the definition:
 Density =
 135 g =
 2.70 g/mL
50 mL

5. Density Activity Find the density of the rock 78.541 g 7.64 g
Find the density of the cube
Find the density of the rock g
