CHEMISTRY GLOSSARY
critical pressure → kritični tlak
Critical pressure is the pressure of a fluid in its critical point; i.e. when it is at its critical temperature and critical volume.
critical temperature → kritična temperatura
Critical temperature is the temperature of the liquid-vapour critical point, that is, the temperature above which a gas cannot be liquefied by an increase of pressure.
cryogenic fractionation → kriogena frakcinacija
Cryogenic fractionation is a process of separation of gases by cooling them until they enter their liquid state. Large scale gas production companies use this method to produce liquid oxygen, liquid nitrogen etc. Gases have different boiling points (the temperature at which they change from liquid to gas). Oxygen has a boiling point of -183 °C, and nitrogen a boiling point of -195.8 °C. Therefore by cooling the gas mixture to -183 °C, the oxygen can be collected as liquid and the nitrogen remains its gaseous form.
joule → džul
Joule (J) is the SI derived unit of energy, work, and heat. The joule is the work done when the point of application of a force of one newton is displaced a distance of one metre in the direction of the force (J = N m). The unit was named after the British scientist James Prescott Joule (1818-1889).
latent heat → latentna toplina
Latent heat (L) is the quantity of heat absorbed or released when a substance changes its physical phase at constant temperature (e.g. from solid to liquid at the melting point or from liquid to gas at the boiling point).
lattice → kristalna rešetka
Crystal lattice is a three-dimensional array of points that embodies the pattern of repetition in a crystalline solid. Don’t mix up atoms with lattice points: lattice points are infinitesimal points in space - atoms are physical objects.
Curie temperature → Curiejeva temperatura
For a ferromagnetic material, Curie temperature or Curie point (TC) is the critical temperature above which the material becomes paramagnetic. For iron the Curie point is 760 °C and for nickel 356 °C. It was named after the French physicist Pierre Curie (1859-1906).
