Still Dense About Density?
Comprehension Skills Interpretative; Applied
The density of a substance is its mass divided by its volume. This exercise will help you be less
dense about density.
The table at the right lists some substances and
their densities. Look at the table carefully.
Arrange the substances in the columns below in the
order of their densities. Begin with the least dense
substances and end with the most dense.
