CHEMISTRY GLOSSARY
astronomical unit → astronomska jedinica
Astronomical unit (AU) is a unit of length employed in astronomy for describing planetary distance. It is the mean distance of the earth from the sun, equal to 1.49597870×1011 m.
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.
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.
unified atomic mass unit → unificirana atomska jedinica mase
Unified atomic mass unit (u or mu) is a unit of mass used in atomic, molecular, and nuclear science, defined as the mass of one atom of 12C divided by 12. Its approximate value is
international system of units → međunarodni sustav jedinica
International System of Units (SI) is the unit system adopted by the General Conference on Weights and Measures in 1960 and recommended for use in all scientific and technical fields. It consists of seven base units (meter, kilogram, second, ampere, kelvin, mole, candela), plus derived units and prefixes.
unit cell → jedinična ćelija
Unit cell is the smallest fragment of the structure of a solid that by repetition can generate the entire structure.
absolute error → apsolutna pogreška
Absolute error is a difference between the obtained value (O) and the real value (μ). It is shown in employed for measuring (g, cm3, ...). For example, if three replicate weights for an object are 1.00 g, 1.05 g, and 0.95 g, the absolute error can be expressed as ±0.05 g. Absolute error is also used to express inaccuracies; for example, if the "true value" is 1.11 g and the measured value is 1.00 g, the absolute error could be written as 1.00 g - 1.11 g = -0.11 g. Note that when absolute errors are associated with indeterminate errors, they are preceded by "±"; when they are associated with determinate errors, they are preceded by their sign.
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.
absorbed dose → apsorbirana doza
For any ionising radiation, absorbed dose (D) is the mean energy imparted to an element of irradiated matter divided by the mass of that element.
