Why is density important

Steel is certainly more dense than water. One could ask the question how a submarine that weighs several tons would be able to float. A submarine takes advantage of air space found within it. The ship's total density is less than water; therefore, it will remain afloat. The captain of the sub opens the hull to allow water in and causes the sub to submerge into the water.

Once the water is released or pumped out , the submarine comes back to the surface. Mass and volume are measures of the quantity of a substance, and as such are defined as extensive properties of matter.

T he ratio of two extensive properties is always an intensive property — one that characterizes a particular kind of matter, independently of its size or mass. These plots show how the masses of three liquids vary with their volumes. Notice that. The only difference between these plots is their slopes. The volume units milliliter mL and cubic centimeter cm 3 are identical and are commonly used interchangeably.

The general meaning of density is the amount of anything per unit volume. What we conventionally call the "density" is more precisely known as the "mass density". Density can be expressed in any combination of mass and volume units; the most commonly seen units are grams per mL g mL —1 , g cm —3 , or kilograms per liter.

The range of densities encountered in the world spans a remarkably wide range, from essentially zero in outer space to the unimaginably huge values found in stellar bodies. These very high densities represent the ultimate limits of how much mass can be packed into a given volume.

We specialize in Karl Fischer moisture titration, general titration, surface tension, density and thermal applications. Our goal is to work with companies to help them make better products. Industries Applications Products. Density is expressed as a ratio of. For our industrial. For liquids, temperature is an important factor that can affect a liquids density.

Therefore we generally will always describe density at a given temperature for comparison purposes. In general, as liquid temperature increases, density decreases. Knowing the density of a liquid serves numerous purposes and can provide valuable information for making decisions. Understanding what density is, what affects density, and how density affects other physical properties is important in using and translating this information into an everyday useful tool.

We can use either a hand-held density meter or benchtop density meter to evaluate a liquids density or specific gravity. We live in a physical world and so it would make sense that we would want to be able.

Having a way to define these physical. A soft-drink containing more sugar for example will have a different higher density than a diet soft-drink. Academic research Density is also used in general as a standard parameter in professional academic research to get to know the special physical behavior of a product. Quality control Another important application of density measurement is quality control, not only in the soft drink or petrochemical industry, but also in the production of alcoholic beverages beer, spirits, wine , fuels including biodiesel and bioethanol , cosmetics, personal care products, pharmaceuticals, and many more.

Filling volume control Whereas some products are quantified by their weight, others are filled, paid, or even taxed by their volume. References H. Fehlauer and H. Rate this article. Cookie settings We use cookies on our website.
