apsolutna metoda

The temperature at which the volume of an ideal gas becomes zero; a theoretical coldest temperature that can be approached but never reached. Absolute zero is zero on the Kelvin ...

apsolutna greška

Chemia; Chemia ogólna

The uncertainty in a measurement, expressed with appropriate units. 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 ...

apsolutna temperatura

Astronomia; Astronomia ogólna

Temperature measured on the Kelvin scale: 0 Kelvin = -273.15 degree Celsius. Absolute temperature is directly related to (kinetic) energy via the equation E = kBT, where kB is ...

apsolutna nula

Astronomia; Astronomia ogólna

The lowest possible temperature, attained when a system is at its minimum possible energy. The Kelvin temperature scale sets its zero point at absolute zero (-273.15 degree on the ...

determinacija

Chemia; Chemia Analityczna

The finding of the value of a chemical or physical property of a compound, such as reaction-rate determination or specific-gravity determination.

apsolutni detekcioni limit

Chemia; Chemia Analityczna

The smallest amount of an element or compound that is detectable in or on a given sample; expressed in terms of mass units or numbers of atoms or molecules.

širina pika

Chemia; Chemia Analityczna

In a gas chromatogram (plot of eluent rise and fall versus time), the width of the base (time duration) of a symmetrical peak (rise and fall) of eluent.

apsorpciometar

Chemia; Chemia Analityczna

1. An instrument equipped with a filter system or other simple dispersing system to measure the absorption of nearly monochromatic radiation in the visible range by a gas or a ...

apsorpciometrijska analiza

Chemia; Chemia Analityczna

Chemical analysis of a gas or a liquid by measurement of the peak electromagnetic absorption wavelengths that are unique to a specific material or element.

particioni koeficijent

Chemia; Chemia Analityczna

In the equilibrium distribution of a solute between two liquid phases, the constant ratio of the solute’s concentration in the upper phase to its concentration in the lower phase. ...
