11. The heat which is required to chang the state of unit mass of a substance from solid to liquid, or from liquid to gass, without change of temperature most substances have a latent heat of fusion and a latent heat of vaporization. ...
PS Sheeran,PA Dayton,TO Matsunaga 摘要: Many studies have proposed phase-change contrast agents (PCCAs) that vaporize to form bubbles ideal for contrast and cavitation. Understanding the phenomena involved with droplet vaporization to determine possible bioeffects will have a profound impact on ...
Boiling water in a pot and water disappearing quickly from surfaces in the summer heat is due to vaporization and evaporation. Although both are phase transitions, the difference between vaporization and evaporation has to do with the temperature at which the phase change takes place. Distinguish Be...
What is the condensation process? What are the three types of heat transfer? Give an illustrative example for each type. What is latent heat? What is the opposite of evaporation? What phase change is evaporation? What is the opposite of condensation?

When liquid transitions to the gas phase, its molecules become even more loosely packed and the intermolecular spaces become larger. How does vaporization occur? It occurs when there is an increase in the kinetic energy of a substance; the intermolecular attraction between the particles reduces and...
Noun1.heat of condensation- heat liberated by a unit mass of gas at its boiling point as it condenses into a liquid; "the heat of condensation is equal to the heat of vaporization" heat of transformation,latent heat- heat absorbed or radiated during a change of phase at a constant temper...

Heat exchanged during a phase change under constant temperature is another way to estimate deS=δq/T. For a solid-liquid transformation after a flow of molar heat of melting ΔHm at a melting temperature Tm and at constant pressure, we have ΔSm=ΔHmTm Similarly, we can estimate the chang...
作者: Vasiliy A. Pozdeev,Sergey P. Verevkin 摘要: Vapor pressures and the molar enthalpies of vaporization of the linear aliphatic alkanediamines H 2N–(CH 2) n–NH 2 with n = (3 to 12) have been determined using the transpiration method. A linear correlation of enthalpies of vaporizati...
