Density

Density is a physical property of a substance that measures its mass per unit volume. It can be calculated by dividing the mass of an object by the volume it occupies. The density of a substance can vary depending on several factors, including temperature and pressure. In general, denser substances are heavier and occupy less space than lighter substances. Density is an important property in many fields, including physics, chemistry, and engineering, and is commonly used to identify and characterize different materials.
