The basic building block of matter is the atom, the smallest unit of an element that can enter into combinations with atoms of the same or other elements. In many substances, atoms are combined into molecules. On earth, matter commonly exists in three states: solids, of fixed shape and volume; liquids, of variable shape but fixed volume; and gases, of variable shape and volume.

Macroscopically, mercury at ordinary temperatures is a silvery liquid which can be poured much like water—rather unusual for a metal. Mercury is also the heaviest known liquid. Its density is 13.6 -fold greater than water. When cooled below –38.9°C mercury solidifies and behaves very much like more familiar solid metals such as copper and iron.

It explains phase diagrams, highlighting the states of matter—solid, liquid, gas—related to temperature and pressure, including melting, boiling points, and the triple point. Additionally, it notes that increased pressure generally leads to solids becoming liquids and describes the sublimation process where solids convert directly to gases.
