### Density

Physical Property

Density: mass divided by the volume of a substance
• Density = mass / volume

ASS

M

OR

D

V

OLUME

Density of solids, liquids, and gases

Density Increase as you move from the gas to solid phases

Gas Liquid Solid

Density usually decreases as Temperature Increases

SIZE does NOT Matter

The Density of an object is the same regardless of size

As long as it is made up of the same composition the density is always the same

Block of Maple

Density = .79 g/mL

If I cut this block in half, what is the density?

Units of Density

Mass: grams (g )

Liquid: volume = milliliters (mL)

Solid: Cubic meters (cm3)

D = m/v

Units : g/mL or

g/ cm3

How do I determine Volume for different objects?

What do I use to determine the volume of a liquid?

What do I use to determine the volume of a solid?

Ruler (metric) = l x w x h (cm x cm x cm = cm3)

What do I do to determine the volume of an irregularly shaped object?

Place the object in the cylinder

Final – Initial = Volume of object

Using the Density Triangle

How do you solve for Mass?

M

X

D

V

• 2. How do you solve for Volume?

M = D x V

V = M / D

• 3. How do you solve for Density?

D = M / V
