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 substance is its mass divided by its volume: Density = Mass ÷ Volume. The units of density depend on the units used for mass and volume, but are usually: g/cm³ (if ...

If something seems very heavy for its size (like a heavy metal object), we say it is more dense. If something seems light for its size (like a bag of cotton or pumice rock), then we say it has low ...

In the hot (yellow) water, the water molecules are slightly further apart than in the cold (blue) water. The hot water is less dense and floats on the cold water. When the cold water is placed on top, ...

What is density, and how does it apply to the universe? From dogs and water to stars and galaxies, this video uses humor and relatable examples to break down one of the most fundamental concepts ...

We measure the geometry of the universe by measuring the average density of matter in space and comparing it to a critical density, which dictates the curvature of space. The gravitational effect ...

I had never before been told I had dense breasts, never been told that breast density increased my risk for breast cancer, never been told that breast density greatly reduces the effectiveness of ...
