Density10
What is “density?” Give a description
and a mathematical formula.
Density 20
If you combine two liquids (with different
densities) that do not mix, what will
the result look like?
Density30
If you mix 5 liquids with different densities in a cylinder, what will the
resulting column look like? Where would the most dense material be? Will
there always be 5 layers?
Density 40
In general, which phase of matter is most dense?
Which is of medium density? Which is of lowest
density?What is an exception to this
generality?
Density50
Explain the connection between the slopes of the lines on a density graph and the density
of the materials.

How can you tell that methane burning in oxygen
is a chemical change?
CH4 + O2 --> CO2 + H2O
Chemical Properties and Changes
