What is what kind of property is density?

Density is a physical property that indicates the amount of mass per unit volume of a substance. In other words, it is the ratio of an object's mass to its volume. The units of density are typically kg/m³ (SI units) or g/cm³ (traditional units). The density of a substance can vary depending on factors such as temperature and pressure. Objects with a high density have a greater mass per unit volume, while objects with a low density have a lesser mass per unit volume. Density is important in many fields such as physics, chemistry, and engineering as it can be used to determine the properties and behavior of different materials.
