If measured in centimeters, the answer will be in cubic centimeters (cm³). Mass is measured in grams. The units for density will be g/cm³. Arrangement of atoms in different metals is similar.

The density of an object or a substance is its mass, divided by its volume. We use the formula: \(density = mass ÷ volume\) to calculate the density of an object or substance. For example ...

points 1 and 2 lie on a streamline, the fluid has constant density, the flow is steady, and there is no friction. Although these restrictions sound severe, the Bernoulli equation is very useful, ...

Students will be able to explain that the density of a liquid has to do with how heavy it is for the sample size. Students will also be able to explain that if a liquid is more dense than water, it ...

The chances of intelligent life emerging in our universe—and in any hypothetical ones beyond it—can be estimated by a new ...

Density and dispersion are two descriptors of populations that can provide insight into processes such as competition and territoriality. Their measurement is therefore fundamental to our ...

The probability density function (PDF) is a statistical expression that defines the probability that some outcome will occur. In this function, the probability is the percentage of a dataset's ...

On an airplane, motions of the air on both small and large scales contribute to turbulence, which may result in a bumpy flight. Turbulence on a much larger scale is important to how stars form in ...

A new FDA rule states that doctors must talk with patients about breast density after a breast cancer screening. But what does this mean? Lara Vukelich is a freelance writer in San Diego ...

Density is usually calculated using a mathematical function of temperature, salinity, and pressure, sometimes called an equation of state. For many years the internationally accepted standard for ...

Breast density is a hot topic in women's health right now thanks to a new rule from the Food and Drug Administration (FDA) that went into effect in September. Under the rule, all women who get a ...
