The density of an object or quantity of matter is its mass divided by its volume. This is usually measured under standard conditions for temperature and pressure: 0°C and 1 atmosphere of pressure.
One factor affecting the density of a material is how concentrated the atoms are in a given volume. In some cases, materials made of atoms with a lower atomic weight have a greater density than those with a higher atomic weight, due to the atoms being more tightly packed. This is especially true for solids.
Non-standard conditions can result in a change of volume, affecting the density of the materials. Also, certain temperatures and pressures can result in a change the state of the matter, which also affects the density.
