CHEMISTRY GLOSSARY

absolute temperature    →   apsolutna temperatura

Absolute temperature denoting a temperature measured on the absolute scale, a scale of temperature based on absolute zero as the lowest temperature.

accelerated corrosion test    →   ubrzana korozija

Accelerated corrosion test is method designed to approximate, in a short time, the deteriorating effect under normal long-term service conditions.

acid-base titration    →   kiselo-bazna titracija

Acid-base titration is an analytical technique in volumetric analysis, where an acid of known concentration is used to neutralise a known volume of a base, and the observed volume of the acid required is used to determine the unknown concentration of the base. An acid-base indicator is used to determine the end-point of the titration.

adenosine triphosphate    →   adenozin trifosfat

Adenosine triphosphate (ATP) is nucleotide that is of fundamental importance as a carrier of chemical energy in all living organisms. It consists of adenin linked to D-ribose).

autoignition temperature    →   temperatura samozapaljenja

Autoignition temperature is the minimum temperature required to initiate or cause self-sustained combustion in any substance in the absence of a spark or flame. This varies with the test method.

Bronsted-Lowry’s acid-base theory    →   Bronsted-Lowryeva teorija kiselina i lužina

Brønsted-Lowry’s acid-base theory: Acid is a substance which gives a proton (protondonor) and base is a substance which accepts a proton (protonacceptor).

chemical technology    →   kemijska tehnologija

Chemical technology is a branch of applied chemistry that concerns technical methods and devices in order to manufacture a chemical product.

body-centered tetragonal lattice    →   prostorno centrirana tetragonska rešetka

Body-centered tetragonal lattice (tetragonal-I), like all lattices, has lattice points at the eight corners of the unit cell plus an additional points at the center of the cell. It has unit cell vectors a=b≠c and interaxial angles α=β=γ=90°.

Celsius temperature scale    →   Celsiusova temperaturna skala

For value of zero in Celsius temperature scale the freezing point of water at a pressure of 101 325 Pa is taken. The boiling point of water at a pressure of 101 325 Pa is taken as another reference point. This range is divided into 100 equal parts, and each part is an equivalent to 1 °C. Units of Celsius temperature scale (°C) and thermodynamic temperature scale (K) are identical

1 °C = 1 K.

first law of thermo-dynamics    →   prvi zakon termodinamike

First law of thermo-dynamics is: Energy can be neither created nor destroyed, but can cross from one shape to another.
