The density of an object or a substance is its mass, divided by its volume. We use the formula: \(density = mass ÷ volume\) to calculate the density of an object or substance. For example ...

If something seems light for its size (like a bag of cotton or pumice rock), then we say it has low density. Mass is the amount of matter in an object. Volume is how much space the object takes up.

Density is a measure of how much mass an object has per unit volume. Density is a compound measure because mass and volume can’t be measured in the same units. Objects denser than water sink ...

To find the volume of an objects like a cube or a box, measure the length × width × height. If measured in centimeters, the answer will be in cubic centimeters (cm³). Mass is measured in grams. The ...

Note: We are purposely using the terms “size” and “amount” instead of “volume” in discussions of density. We are also using “heavy”, “light”, and “weight” instead of “mass”. If your students have ...

The physical properties of seawater include both 'thermodynamic properties' like density and freezing point ... These physical properties include the volume-to-mass ratio of a solid, liquid ...
