Figure 1. An XKCD comic showing the comparative energy density of Uranium. Energy density is the amount of energy that can be stored in a given mass of a substance or system. The higher the energy density of a system or material, the greater the amount of energy stored in its mass. Energy can be stored in many different types of substances and systems. A material can release energy in four types of reactions.
density is the mass per unit volume. This means that the density of any solid, liquid or gas can be found by dividing it's mass in kilograms by it's volume in cubic metres.he formula for density is. Density = mass/volume. So something that is very heavy but doesn't take up much space is considered to have a high density (like lead), but something that is light and takes up a lot of space has a low density (like feathers).
