Density Definition Explained
Mass density, often referred to simply as density, is a fundamental property of matter.
It quantifies how tightly matter is packed together within a substance.
Formal Definition
Density is defined as the mass of an object or substance divided by the space it occupies, its volume.
Mathematical Representation
The formula for density is:
\( \rho = \frac{m}{V} \)
- \(ρ\) is the symbol for density.
- \(m\) represents the mass of the material.
- \(V\) represents the volume occupied by the material.
Identifying the Correct Term
The formula clearly shows that density is calculated as mass divided by volume. Therefore, the definition corresponds to 'mass per unit volume'.
