The density of a solid, liquid or gaseous body is one of the most important parameters in any body. Density in its definition is the measure of how much a body occupies in relation to what it weighs, i.e. density=mass\/volume. Therefore, the measure of density is defined by kg\/L, or Kg\/cm3. In short, the same weight of a very dense body will take up very little and a body that is not very dense will take up a lot.<\/p>\n
Density, especially for liquids and gases, varies as a function of temperature and pressure. Absolute density is defined as the density measured at 1atm and 4\u00baC<\/strong>. In the case of the water<\/a> this density corresponds to 1000Kg\/m3 or 1Kg\/L. This water density value corresponds to distilled water; as the salinity of the water varies, its density varies. The density of water also decreases as the temperature increases. At 20\u00baC this density is 0.998Kg\/L.<\/p>\n In many cases, the value of relative density, <\/strong>This compares the density with another liquid, indicating by what proportion it is more or less dense. In this case, the relative density value would be unitless, as it would be a ratio factor. Water is commonly used as a reference value. The measure of relative density is used for example when talking about oil density<\/a>compared to that of water.<\/p>\n<\/h2>\n
