What are three important facts about density? Density, the weight of an object divided by its volume, is a property of all matter, including solids, liquids and gases. The value of an object’s density depends on what it’s made of as well as its temperature; for example, lead weights are denser than feathers, and cold air is denser than hot air.

How does density affect matter?
