To find the volume of an objects like a cube or a box, measure the length × width × height. If measured in centimeters, the answer will be in cubic centimeters (cm³). Mass is measured in grams. The ...

The same mass takes up a bigger volume - this means the gas is less dense. Density also depends on the material. A piece of iron with the same dimensions as a piece of aluminium will be heavier ...

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 in ...

Density describes how closely packed the particles are in a solid, liquid or gas. There is little difference between the density of a liquid and its corresponding solid (eg water and ice). This is ...
