Enthalpy of vaporization is one of the most important thermophysical properties due to its extensive applications in science and industry. Prediction of the enthalpy of vaporization as a function of temperature has been the topic of many studies in the past decades. Among numerous models available ...
In Steam Tables, specific enthalpy is referred as hw for water, hv for vapor, and hev=(hv–hw)=hfg, for enthalpy of vaporization. Table 2.17. Specific Enthalpy h, (kJ kg−1) of Various Salt Solutions at 100°C Concentration (‰)NaClKClMgCl2Na2SO4MgSO4Seawater Pure (H2O) 4.214 ...
Conversely, entropy changes become particularly significant in processes where temperature and disorder vary, such as in melting, vaporization, and mixing. 6 Calculations of enthalpy are often used in designing energy-efficient systems, like engines and refrigerators, to maximize the energy output from ...
Latent heat is the heat when supplied to or removed from air results in a change in moisture content - the temperature of the air is not changed. Liquids - Latent Heat of Evaporation Latent heat of vaporization for fluids like alcohol, ether, nitrogen, water and more. ...
Heats of Fusion and Vaporization Heat of Fusion (Hf) is the energy required to melt a solid and change it to a liquid (or the reverse change a liquid to a solid….just a different sign….energy flow) Heat of Vaporization (Hv) is the energy required to change a liquid into a gas (...
For most pure substances, b covers the range from 0 to 1. Only one negative value stands for the quantum fluid helium because of its enthalpy of vaporization being experimentally not a monotonic function of the temperature in the range near the triple point....
The theoretical calculation of enthalpy of vaporization based on Clapeyron equation involves the vapor-pressure-temperature correlation and the equation of state, and hence an explicit formula is unavailable. The formula for enthalpy of vaporization derived from the corresponding state principle, although ...

We find that, under some reduction using critical data, the experimental curves of vaporization enthalpy versus the saturated temperature will overlap with each other, i.e. the universal behavior experimentally holds for the temperature-dependent vaporization enthalpy, in the temperature range from the ...
