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 Increase as you move from the gas to solid phases
Gas Liquid Solid
Density usually decreases as Temperature Increases
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?
Mass: grams (g )
Liquid: volume = milliliters (mL)
Solid: Cubic meters (cm3)
D = m/v
Units : g/mL or
What do I use to determine the volume of a liquid?
Graduated cylinder, beaker, flask
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?
Use a graduated cylinder
Take the initial reading
Place the object in the cylinder
Take the final reading
Final – Initial = Volume of object
How do you solve for Mass?
M = D x V
V = M / D
D = M / V
