FORMULABANK

Density is a physical property that expresses the mass of an object relative to its volume. It is commonly used in both science and engineering to describe how much matter is packed into a given space.

Formulas:

• $\mathrm{Mass}=\mathrm{Density}\cdot \mathrm{Volume}$
• $\mathrm{Density}=\frac{\mathrm{Mass}}{\mathrm{Volume}}$
• $\mathrm{Volume}=\frac{\mathrm{Mass}}{\mathrm{Density}}$

Density Explained:

Density tells us the weight of a substance relative to its volume:

• 1 cm³ of the substance weighs in grams.
• 1 dm³ of the substance weighs in kilograms.
• 1 m³ of the substance weighs in tons.

In other words, the density value gives us a quick way to estimate how heavy a specific volume of a material will be. The unit used depends on the scale of the volume being considered.

These values represent average densities for the materials listed, and they can vary slightly depending on temperature and pressure.
