Upon freezing, the volume of mercury decreases by 3.59% and its density changes from 13.69 g/cm 3 when liquid to 14.184 g/cm 3 when solid. The coefficient of volume expansion is 181.59 × 10 −6 at 0 °C, 181.71 × 10 −6 at 20 °C and 182.50 × 10 −6 at 100 °C (per °C). Solid mercury is malleable and ductile, and can be cut with a knife ...
Chain-melted state: Metals, such as potassium, at high temperature and pressure, present properties of both a solid and liquid. Wigner crystal: a crystalline phase of low-density electrons. Hexatic state, a state of matter that is between the solid and the isotropic liquid phases in two dimensional systems of particles. Ferroics
A vapor can exist in equilibrium with a liquid (or solid), in which case the gas pressure equals the vapor pressure of the liquid (or solid). A supercritical fluid (SCF) is a gas whose temperature and pressure are above the critical temperature and critical pressure respectively. In this state, the distinction between liquid and gas disappears.
A unit of volume is a unit of measurement for measuring volume or capacity, the extent of an object or space in three dimensions. Units of capacity may be used to specify the volume of fluids or bulk goods, for example water, rice, sugar, grain or flour.

A line graph representing the change between different phases of matter, typically from a gas to a solid or a liquid to a solid, as a function of time and temperature; e.g. showing how the temperature of a liquid substance changes over time as it condenses below its freezing point. coordinate chemistry coordinate covalent bond See dipolar bond.
The Latin term, during the Roman Empire, was aes cyprium; aes was the generic term for copper alloys such as bronze. Cyprium means "Cyprus" or "which is from Cyprus", where so much of it was mined; it was simplified to cuprum and then eventually Anglicized as "copper" (Old English coper/copor). · Symbol Cu is from the Latin name cuprum ("copper").
