For the temperature range of 50°C to 374°C (the critical point of water) the value of x appears to be 1·2. Other liquids to which application of the formula gives satisfactory results are intermediates in the preparation of silicones, besides mixtures of water and sulphuric acid.doi:10.1016/0009-2509(56)80040-7J.

The equilibrium pressure, peq, of a hydride system is related to the changes ΔH and ΔS in enthalpy and entropy as a function of temperature. The relationship can be described by the Van't Hoff equation: (6.8)ln(peqpeq0)=ΔHR.T-ΔSR For the construction of a Van't Hoff plot (...
How are vapor pressure and temperature related?Vapor pressure and Temperature:At a given temperature, every liquid exit in equilibrium with its vapour. The pressure exerted by its vapor is known as vapor pressure. Vapor pressure increases with temperature. The relationship between vapor pressure and ...
The absolute pressure -pabs– is measured relative to theabsolutezero pressure– the pressure that would occur at absolute vacuum. All calculation involving the gas laws requirespressure(andtemperature) to be in absolute units. Gauge Pressure ...

A typical phase diagram for a single-component material, exhibiting solid, liquid and gaseous phases. (Picture by Matthieumarechal CC BY-SA 3.0). The Clausius-Clapeyron equation is a derivation of this formula. It describes the relationship between the vapor pressure and the temperature of a ...
The experimental volume–volume (V–V) data of copper and rhenium are shown in Fig. 4, together with a V–V relationship (solid line in Fig. 4) between copper and rhenium. This V–V relationship is obtained using EoS parameters of both Cu and Re in Table 2. This relationship itself ...
Anomalous behavior is observed for the intensities of the 177 cm−1 and 1052 cm−1 peaks from 390 K to 420 K, consistent with the contraction temperature range observed in our NTE experiment. This finding demonstrates a close relationship between NTE behavior and phonon anomalies resulting ...
