What is a simple statement of density

density

We will deal with the density of bodies in this article. We will explain to you what is meant by density and how to calculate it. This article belongs to the physics / mechanics category.

Before we get into density, you should read the following headings. If these topics seem unfamiliar to you, be sure to read them up. Without this knowledge, you may have problems understanding this article.

Density of fabrics

The density - more precisely the mass density - of a body is understood as the ratio of its mass to its volume. The density is usually given in grams per cubic centimeter or kilograms per liter. To put it more clearly, density says whether a body is light as a feather or heavy as a piece of iron for its size. The density is calculated as follows:

  • "ρ" is the density [in g / cm3 or kg / l]
  • "m" is the mass [in g or kg]
  • "V" is the volume [in cm3 or l]

Example:

We want to calculate the density of gasoline. We know: 3500g gasoline takes 5000cm3 Room. How big is the density?
