![]() When we increase the temperature of an object, its volume increases and thus, density decreases. The density of an object represents its compactness, or mass per given volume of a substance, and is most commonly represented as grams per milliliters. Density can be calculated by its formula which is mass divided by volume. The SI unit of density is kg/m³ unit kilogram per cubic meter. It is represented by the letter D and the symbol, ‘rho’. When we apply pressure to an object, its volume decreases and thus, density increases. Density is the measurement of the mass of an object per unit volume. The density of substance varies with temperature and pressure.

The ratio of the mass of an object to its volume. From this we can conclude that for the same mass of two objects, higher the volume of an object, lesser is its density. A measure of how tightly the matter in a substance is packed together. This is because the density of the metal nail is more than that of the block of wood. If we drop a block of wood and a metal nail having the same mass in water the wooden block floats and the metal nail sinks in water. Collins COBUILD Key Words for Chemical Engineering. The density of one kilogram and two kilogram of water is the same. Why is density considered a physical property rather than a chemical property of matter A physical property of a substance is a property that can be. Density is the quantity of mass per unit volume of a non-porous solid. The density of a substance does not depend on the amount of the matter. The property of a system which is independent of the amount of matter present in the system is known as an intensive property. The electron density function, ( r) (measured in e Å 3 ), allows us to know the molecular structure from which a crystal is made the electron density is concentrated in the vicinity of the nucleus, showing peaks at the electron density maxima (atomic positions) and taking relatively low values out of the atomic positions. The mathematical expression for density is as follows: Different substances have different densities. If two substances have equal volumes, then the substance with more mass is more dense.ĭensity is defined as the ratio of mass of the object to the volume of the object. Density expresses the relationship between the mass and the volume of matter. Definition: Density depends on how atoms or particles are arranged in matter in a specific volume. Density defined in a qualitative manner as the measure of the relative 'heaviness' of objects with a constant volume. Apparent density is a property of partitioned solids, such as powders and granules, and is often used in the mining, food and chemical industries. BSL Chemistry Glossary - density - definition. Hint: We know that density is a physical property of matter. DENSITY is a physical property of matter, as each element and compound has a unique density associated with it. ![]()
