Specific density

The specific density of a material or liquid is the term used to describe the unit mass of a material or liquid.

The technical term for specific density, also referred to as density, is ρ and is measured in kg/m³.

The specific heat capacity is dependent on the temperature of the medium. The specific density of water in a heating system at a temperature of between 20–90 oC is 1,000 kg/m³.
