Volumetric mass is another term used to describe the body density, where the body density or volumetric mass reflects how much the link that connects between the size and mass, as the mathematical relationship that express mass is (density (P Ru) = body / body size block) It is this relationship, we find that the density increases the increasing body mass while carrying the body density decreases in size. The unit volumetric mass is a unit of mass divided by unit volume, and often are in grams per cubic centimeter. For example, if we had a body mass of 500 grams and the size of 50 cubic centimeters, the intensity of this body and build on the previous relationship is equal to (mass / volume = 500 g / 50 cubic centimeters = 10 grams / cubic centimeter).
Of the most influential factors in the density is the heat factor which exposed body, as the high temperature helps the body to stretch and are too large to lose the element attraction particles that are between the molecules so that increasing distances and very significantly between these molecules, while the second factor of these factors is the increased pressure and dramatically or also decreasing dramatically, the great pressure exerted on the body leads to a convergence of molecules from each other, which will work to decrease the size and dramatically, and here emerged we have what is known as the absolute density, which means the body density at the temperature zero percentile. For example, an estimated density of the air at a temperature of zero percentile temperature for approximately 1.293 grams per cubic centimeter, while the density of the body at a temperature of 25 ° C is about 1.18 grams per cubic centimeter The air density at -10 ° C amounts to 1.34 grams per cubic centimeter, and this values note how the effect of temperature dramatically and significantly on the amount of body density, the more the temperature rises, the volume will increase this value means ateliosis density as we have said previously.
There is a term known qualitative density, which expresses the ratio between the density of the body which was to the density of water, under conditions 1 D.j and 4 degrees centipedes and there is no unit for the density of quality, if the ratio is greater than 1, it means that the density of this material is greater than the density water, but if you say the quality 1 this density means that the density of this body is less than the density of water.
