When materials have higher density than that of water, they sink. Conversely, materials with lower density float. A good example is ice floating in a glass of water. This property is often used in daily life. In most cases hollow objects, made from more dense materials than water for structural reasons, contain air, which is less dense than water. This allows the vessel to float, as long as enough air is c

Density of Common Substances

Overview

Density indicates how much of the mass of a substance fits in a given volume. In SI it is measured as kg/m³, but alternative measures are also used, like g/cm³ and kg/L, for example. In everyday life the equivalent units of g/cm³ and g/mL are most commonly used.

Factors Affecting Density

Density varies for substances depending on their temperature and pressure. Higher pressure causes the molecules of the substance to become packed more densely within the same volume, increasing the density. Increase in temperature, on the other hand, generally causes the molecules to become more spaced out, thus decreasing the density. This is not always true, however. For example, the density of ice is lower than that of water. When most other liquids solidify, the space between the molecules decreases. When water molecules freeze, the bonds within the molecules change intensity, and form a crystal. Space between molecules increases, volume of the water expands, and the density decreases. Expanded volume of ice is why water that freezes in the house pipes in winter may make the pipes burst.

Density of Water

When materials have higher density than that of water, they sink. Conversely, materials with lower density float. A good example is ice floating in a glass of water. This property is often used in daily life. In most cases hollow objects, made from more dense materials than water for structural reasons, contain air, which is less dense than water.
