# What happens to density if the mass increases at constant volume?

Aug 22, 2017

If there is greater mass $m$ within a given volume $V$, the density $D$ increases.

#### Explanation:

$D = \frac{m}{V}$

If the volume stays the same, then an increase in mass will cause an increase in density.

However, an increase in mass along with an increase in volume can give rise to no increase in density, which would describe an intensive property.

An intensive property, like density, does not depend on the amount of substance present (whereas mass and volume are both extensive).
