Density refers to the amount of matter that is present in a certain volume of a certain. Density is the measure of the how heavy of molecularly dense is the substance. Density of a particular substance can be obtained by dividing the mass of a substance by the volume of a substance. It has been found that the SI unit of the concept that is density is kilo per cubic metre. It can be said that the density of a particular substance is directly proportional to the weight of the substance. The latter implies that a substance that is heavier has higher weight. This, can be explained by taking a simple examples. Suppose there are two pots of the same high and volume. They will look same from outside. However, the pot that is hollow from within will weigh kisser than the one that contains mud. The density of a substance of the same height and diameter can be obtained y checking the weight of the same. It is beneficial in terms of adjudging the quality of materials such as gold or platinum or any material of the same sort. However, it should be noted that the density of other substances are different. The density of wood would be different from that of water. The density of water would be different from that of tungsten the density of almost every component that formulate the abiotic components of the nature are different. The quality of gold is tested by checking the density of the same. The latter is an expensive material and evaluation of the density of the same helps in identification of the quality of the same. Density of substances are viable in terms of operation of all the components of industrial activities. Checking the density of materials determine the viability of the ultimate product that is formed and thus it can be said that adjudging the same helps industrial units in gaining effectiveness in deriving the ultimate desirable product. Even though density of a substance is related to that of weight of a substance, it can be directly linked to the volume of then substance. Thus, density of a substance helps in gaining advantage in understanding the effectiveness of operation of the industries. It is a concepts that must be instated into the operation of all the organisations that are concerned with the industrial manufacturing. Although the density is necessary for gaining an understanding regarding the quality of a substance, there are instances when materials of catering to the requirement of material that need to be of lower density. Thus, density of a substance is a concept that should not be ignored and should be catered to effectively. It is a concept that shapes the basic laws of physics and thus, is one of the most important concept that revolves around the development of understanding of basic theories in physics.
