CHEMISTRY GLOSSARY
molar enthalpy of evaporation → molarna entalpija isparavanja
Molar enthalpy of evaporation (Δl gH) is a change of enthalpy during evaporation divided by molarity of a liquid, and is equal to the heat energy spent when the evaporation is conducted under constant pressure, Δl gH=Q.
molar quantity → molarna veličina
Molar quantity is often convenient to express an extensive quantity (e.g., volume, enthalpy, heat capacity, etc.) as the actual value divided by the amount of substance (number of moles). The resulting quantity is called molar volume, molar enthalpy, etc.
halocarbon → halogenirani ugljikovodik
Halocarbon is a compound containing no elements other than carbon, one or more halogens, and sometimes hydrogen. The simplest are compounds such as tetrachloromethane (CCl4), tetrabromomethane (CBr4), etc. The lower members of the various homologous series are used as refrigerants, propellant gases, fireextinguishing agents, and blowing agents for urethane foams. When polymerized, they yield plastics characterized by extreme chemical resistance, high electrical resistivity, and good heat resistance.
hardness → tvrdoća
Hardness is the resistance of a material to deformation of an indenter of specific size and shape under a known load. This definition applies to all types of hardness scales except Mohs scale, which is a based on the concept of scratch hardness and is used chiefly for minerals. The most generally used hardness scales are Brinell (for cast iron), Rockwell (for sheet metal and heat-treated steel), Knoop (for metals).
hydration → hidratacija
Hydration is addition of water or the elements of water (i.e. H and OH) to a molecular entity. The term is also used in a more restricted sense for the process:
infrared radiation → infracrveno zračenje
Infrared radiation is an electromagnetic radiation within the area from 1.0 μm to 300 μm, and is responsible for the transmission of radiant heat.
Peltier effect → Peltierov efekt
Peltier effect is the absorption or generation of heat (depending on the current direction) which occurs when an electric current is passed through a junction between two materials.
racemisation → racemizacija
Racemisation is a conversion, by heat or by chemical reaction, of an optically active compound into an optically inactive form which half of the optically active substance becomes its miror image (enantiomer).
radiation → radijacija
The process of heat transfer which occurs through empty space and can also occur in matter, in the form of electro-magnetic (EM) waves, is called radiation or radiant heat. Whenever EM radiation is emitted and then absorbed, heat is transferred. This principle is used in microwave ovens, laser cutting, and RF hair removal.
