Intensive and Extensive Properties

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

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

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
