Density

What is density?

Back

Density is a measure of how much mass is contained in a given volume. It is calculated using the formula: density = mass / volume.

What is the formula for density?

Back

density = mass / volume

Why do some substances float on water?

Back

Substances float on water because they are less dense than water.

What is an example of a substance that is more dense than water?

Back

A rock is an example of a substance that is more dense than water.

Front

How does temperature affect density?

Back

Generally, as temperature increases, density decreases because substances expand.

Front

What is the relationship between mass and volume in terms of density?

Back

Density is directly related to mass and inversely related to volume; if mass increases while volume stays the same, density increases.
