Quiz
Intensive vs. Extensive properties of matter
Density
Intensive vs. Extensive Properties of Matter
Objective:
09/06/16
SWBAT compare and contrast intensive and
extensive properties of matter.
Intensive Properties
Do not depend on the amount of matter present.
Ex: Color
Group Discussion
With your group, discuss ideas that can be
classified as intensive properties.
Intensive Properties
Do not depend on the amount of matter present.
Ex:
●
●
●
●
●
●
●
Color
Odor
Lust: How shiny a substance is
Hardness
Texture
Melting/Freezing/Boiling Point
Density
Extensive Properties
Depend on the amount of matter present.
Ex: Mass: the amount of matter in an object
Group Discussion
With your group, discuss ideas that can be classified as
extensive properties.
Extensive Properties
Depend on the amount of matter present.
Ex:
● Mass: (grams) the amount of matter in an object
● Weight: A measurement of the gravitational force of
attraction of the earth acting on an object
● Volume: (L or ㎤) the amount of space a substance
occupies
● Length
Density
● It is a measure of how tightly packed and how
heavy the molecules are in an object.
● Amount of matter within a certain volume
Density = mass
volume
Manipulating the equation
The Density Triangle
Density Example 1
Marcos has a paper clip. It has a mass of 9 grams, and a
volume of 3 ㎤. What is its density?
Density Example 2
Mercury metal is poured into a graduated cylinder, that holds
exactly 22.5 mL. The mercury used to fill the cylinder weighs
306.0 grams. From this information, calculate the density of
mercury.
Density Example 3
What is the mass of the ethyl alcohol that exactly fills a 200.0
mL container? The density of ethyl alcohol is 0.789 g/mL.
