CHEMISTRY GLOSSARY Clapeyron equation Clapeyronova jednadžba Clapeyron equation (also called the Clausius-Clapeyron equation) is a relation between pressure and temperature of two phases of a pure substance that are in equilibrium, dpdT =
A kinetic study has been carried out (Pagsberg et al.) by monitoring selected absorption signals of the rovibration transitions of the ν3 and ν5 IR bands of HONO as a function of time for different partial pressures of ammonia at a total pressure of 20 mbar. At 298 K the rate const...
Simple and exact expressions have been found for the compressibility and pressure equations of state predicted by the Percus—Yevick equation for hard spheres. The equations of state are in good agreement with the machine calculations of Wainwright and Alder, and Wood, Parker, and Jacobson.关键词...
For instance, assuming k≥ 2, using Pk finite elements to approximate the velocity and Pk−1 finite elements to approximate the pressure is acceptable. Likewise, using Qk elements for the velocity and Qk−1 elements for the pressure on meshes composed of quadrangles or cuboids is admissible...

The universal gas constant units must match the units used for other variables in the equation. Pressure (P) Pressure can be measured with many different units. The most common are: atmospheres (atm), pounds per square inch (psi), torr (torr), pascals (Pa), and millimeters of mercury (...

Equations of state (EoS) are used for calculations of thermodynamic properties of mixtures in industry and in academia, especially for systems at high pressures. The term “high pressure” refers to pressures high enough to significantly alter the thermodynamic properties of both liquid and vapor pha...
In 1924, Stern made corrections to the theory accounting for the layer of counterions nearest the surface. When quantitative colloid chemistry came into existence, the “Kruyt” school (Verwey and Overbeek, 1948) routinely employed the Gouy–Chapman and Stern theories to describe the diffuse layer...
