The following are some other units:įurthermore, density is measured in grams per cubic centimeter (g/cm^3) in the cgs system.Īn object's mass density is defined as its mass per unit volume. Other density units, such as metric tonnes and liters, are also used, despite the fact that they are not part of the SI. The SI unit of density, on the other hand, is kilogram per cubic meter (kg/m^3). The density of water (about 1 gram/cubic centimeter) is commonly used as the reference for estimating the density of other substances. Varied substances have different densities, which implies they weigh differently for the same volume.Įvery substance has its own density.It indicates how weighty an object is at a constant volume in qualitative terms.Density is defined as the connection between a substance's mass and the volume it occupies.Although the SI unit of density is kg/m3, we use g/cm3 for solids, g/ml for liquids, and g/L for gases for convenience. Density definition chemistry free#This is because solids have closely packed particles, liquids have materials that allow particles to slide around one another, and gases have particles that are free to move around. Liquids have a lower density than solids, while gases have a lower density than liquids. Sparse is the polar opposite of dense, and examples of sparse materials include glass, bamboo, aluminium, and styrofoam. Dense materials are more likely to ‘feel' weighty or rigid. Dense stuff includes a variety of rocks and minerals. Density example:ĭense materials include iron, platinum, and lead. The mass per unit volume is how it's defined.ĭensity Formula = m/V, where is the density, m is the object's mass, and V is the object's volume. The density of a material is the measurement of how densely it is packed together. Density is symbolised by the symbol ρ, which can alternatively be represented by the letter D. If you know the formula and are familiar with the units, calculating density is simple. Archimedes, a Greek scientist, discovered the density principle. It is an object's one-of-a-kind physical attribute. The density of matter is a measure of how firmly stuff is packed together. The density of a material is defined as its mass per unit volume. The density of a material indicates how dense that material is in a particular area. What is density? Or define density or definition of density Although the Latin letter D can also be used, the most commonly used sign for density is rho. Iron, lead, and platinum are examples of dense materials.Ī substance's density is defined as its mass per unit volume. This equation can be used to compute the density of an object or substance: The mass in kilogram divided by the volume in metres cubed equals the density in kilogram per meter cubed. In Physics, the meaning of density of a substance or thing is a measure of how compact its mass is. Iron, lead, and platinum are examples of dense materials. It also means that a vast cube of Styrofoam and a tiny cube of lead can weigh the same amount. Density definition refers to the fact that if you weigh two identical cubes constructed of different materials, they will usually not weigh the same.
