CONSTRUÇÃO DA CURVA DE EQUILÍBRIO LÍQUIDO-VAPOR USANDO UMA EQUAÇÃO DE ESTADO CÚBICA: USO DO EXCEL NO ENSINO DE FÍSICO-QUÍMICA

open access: yesQuímica Nova, 2016
Cubic equations of state are able to predict the liquid-vapour coexistence curve of volatile substances. However, this property is rarely used to teach Physical Chemistry because solving the resulting equations require numerical technics and many ...

Modelling of an industrial moving belt chemical vapour deposition reactor forming SiO2 films [PDF]

open access: yes, 2005
In order to improve the efficiency of an industrial atmospheric pressure chemical vapour deposition (APCVD) moving belt reactor depositing silicon dioxide SiO2 films from tetraethoxysilane Si(OC2H5)4 (TEOS) andozone O3, a 2D simulation model based on the

HFO1234yf Condensation Inside A Brazed Plate Heat Exchanger [PDF]

open access: yes, 2012
This paper presents the heat transfer coefficients and the pressure drop measured during HFO1234yf condensation inside a brazed plate heat exchanger: the effects of saturation temperature, refrigerant mass flux and vapour superheating are investigated ...

Thermodynamic properties of the liquid Hg-Tl alloys determined from vapour pressure measurements [PDF]

open access: yesJournal of Mining and Metallurgy. Section B: Metallurgy, 2002
The partial vapour pressure of mercury over liquid Hg-Tl liquid solutions were determined in the temperature range from 450 to 700 K by direct vapour pressure measurements carried out with the quartz gauge. From the measured ln pHg vs.

The influence of particle composition upon the evolution of urban ultrafine diesel particles on the neighbourhood scale [PDF]

open access: yesAtmospheric Chemistry and Physics, 2018
A recent study demonstrated that diesel particles in urban air undergo evaporative shrinkage when advected to a cleaner atmosphere (Harrison et al., 2016).

The relation between the vapour pressure and water content of soils

open access: yes, 1925
Much of the modern work on the physical properties of soil has been interpreted on a colloidal basis and more recently this hypothesis has been extended by the thermodynamical studies of Wilsdon and also by the investigations of two of us on an indirect ...

The impact of climate warming on the air humidity characteristics and their long-term perspective in Poland

open access: yesGeographia Polonica
Long-term changes in saturation, actual water vapour pressure, and saturation deficit in Poland were studied. For that purpose, data from 48 meteorological stations covering the 1966-2020 period were used.
