What is
Density? Density is how much ‘stuff’ is packed into a particular area.
For
example, if we have 13 balls in a box and we have the same box with 27
identical balls inside it. We say the box with 27 balls has higher density than
the box with 13 balls.
Density
is a fundamental property of matter. Density is defined as mass divided by unit
volume. It is measured in grams per cubic centimeter or kilograms per cubic
meter. The Greek letter rho, is the symbol for density.
Density,
ρ = Mass ÷ Volume
So,
two liquids can take up the same amount of space(volume) but can have
completely different masses. If liquid A has a higher mass, MORE of that liquid
is in that space and therefore is denser. If liquid B has a lower mass, LESS of
that liquid is in that same space and is therefore less dense than liquid A.
All
liquids in your tower have similar volumes but they have different densities.
What does that mean? That means that each liquid has a different amount of mass
in that volume. The liquids with the highest density are at the bottom, and the
ones with the lower density are on top of each other. So, which of the liquids
is most dense? And which is least dense?
