CHEMISTRY GLOSSARY
cgs system of units → cgs sustav jedinica
Cgs system of units is a system of units based upon the centimetre, gram, and second. The International System (SI) has supplanted the cgs system.
crystallisation → kristalizacija
Crystallisation is process in which the melted substance from a saturated solution turns into solid substance (crystal).
crystallography → kristalografija
Crystallography is a science that studies structure, shapes, crystalline properties and laws of their creation.
fractional crystallisation → frakcijska kristalizacija
Fractional crystallisation is a method of separating a mixture of soluble solids by dissolving them in a suitable hot solvent and then lowering the temperature slowly. The least soluble component will crystallise out first, leaving the other components in the solution. By controlling the temperature, it is sometimes possible to remove each component in turn.
Gaussian system of units → Gaussov sustav jedinica
Gaussian system of units is a hybrid system used in electromagnetic theory, which combines features of both the electrostatic cgs subsystem (esu) and electromagnetic cgs subsystem (emu). With three base units, it uses em units in magnetism and es units in electrostatics. This involves using the constant c (the velocity of light in vacuum) to interrelate these sets of units.
heat of crystallization → toplina kristalizacije
Heat of crystallization or enthalpy of crystallization is the heat evolved or absorbed when one mole of given substance crystallises from a saturated solution of the same substance.
open system → otvoreni sustav
Open system is a system which can exchange matter and energy with the environment.
groups in periodic system of elements → skupine periodnog sustava
Periodic system of elements is divided into 18 groups of chemical elements. Elements belonging to the same group have a same number of valence electrons and similar chemical properties. Elements of main groups are in 1., 2., and in groups 13. to 18. Different groups of elements can be named according to the first element in the group (elements of boron group, elements of carbon group), or they have some special names (noble gases, halogenic elements, halyde elements, earthalkali and alkali metals).
system → sustav
System is the region under consideration, as distinguished from the rest of the universe (the environment). Systems may be separated from environments by boundaries that prevent the transfer of mass (a closed system), of heat (an adiabatic system), or of any energy (an isolated system). Systems that exchange mass with the environment are open systems.
