Sentence examples for vapour density from inspiring English sources

Dumas greatly improved the method of determining the vapour density of substances (and thus their relative molecular masses), and he developed a combustion method for determining nitrogen in organic compounds.

In this data article, analysis of surface water vapour density in Southeast, Nigeria were reported.

In this data article, analysis of surface refractivity and water vapour density in Southeast, Nigeria were reported.

Corrections to the predictions for the spatial distribution of vapour density around a sessile droplet and the evaporative flux of vapour at the interface are obtained.

Descriptive statistics were used to show an increase in monthly variation of surface water vapour density (SWVD) minimum value of about 7.15 g/m3 at Enugu in January to maximum value of about 21.96 g/m3 at Onitsha in April.

The data are listed according to vapour density values (which is the maximum concentration of the analyte in the air at a given temperature at equilibrium), calculated by multiplying the vapour pressure and molecular weight and dividing by the gas constant (8.314 J K-1 mol-1) multiplied by the temperature in Kelvin.

He also developed a method for determining the molecular weights of liquids from vapour densities.

Devising a method of determining the vapour densities of inorganic substances at high temperatures (1871), Meyer found that diatomic molecules of iodine and bromine dissociate into atoms upon heating.

A paper that suggested a way out of this difficult situation was published as early as 1811 by the Italian physicist Amedeo Avogadro, who used vapour densities to infer the relative weights of atoms and molecules and suggested that elementary gases must consist of molecules with more than one atom.

We have already mentioned the appeal to the equal numbers hypothesis and vapour densities.

This legitimated the use of vapour densities for the determination of relative molecular weights.
