Students will be able to explain that the density of a liquid has to do with how heavy it is for the sample size. Students will also be able to explain that if a liquid is more dense than water, it ...

The difference is mostly due to the fact that air is a gas and the water is a liquid, because density depends a lot on the state of matter. In a solid, the particles are tightly packed ...

Density describes how closely packed the particles are in a solid, liquid or gas. There is little difference between the density of a liquid and its corresponding solid (eg water and ice).
