Density

1
Density

• The make up and structure of all matter!!!

2
Everyone Ever Tell You Your Dense?

• Well, you all are

Because you all have these two properties
You are made up of matterwhich means you have
MASS
You all have VOLUMEwhich means you take up space
3
When You Combine Mass and Volume, you get

• Density

A measure of the amount of matter that occupies
a given amount of space
SPACE
Amount of Matter

So now your gonna say we need more units, right?

• Right!!!!

Even An Equation
M
Units for Density Grams per cubic
centimeter g/cm3
D
V

Wanna See An Example Question?

• An unknown object has a mass of 15.0 grams and a
  volume of 5.0 cm3. What is the density of this
  object?

Density Mass Volume
Density 15.0 grams 5.0 cm3
Density 3.0 g/cm3
8
Your Turn!!!

• An unknown liquid has a volume of 6.0 cm3 and a
  mass of 6.0 grams. What is the density of this
  liquid?

Density Mass Volume
Density 6.0 grams 6.0 cm3
Density 1.0 g/cm3
GOOD JOB!!!

How Can We Compare Densities?

• Wellthere are a known set of densities on record
  throughout the world

Density of Water
1.0 g/cm3
Gives Us Buoyancy
10
Buoyancy

• An objects ability to float in water

Density Greater than 1.0 g/cm3
Sinks
Density Less than 1.0 g/cm3
Floats
