heats of fusionand vaporization are the heat inputs required to produce the phase changes. The word latent means hidden, when the phase change is from solid to liquid it is thelatent heatof fusion, and when the phase change is fromliquid to gas, it is the latent heat of vaporization. ...
because the substance has in fact gone through o phase changes. The energy possessed by a molecule in the gas phase is of no difference from one that es from melting and boiling. Generally the latent heat of sublimation is just the sum of the latent heats of fusion and vaporiz...
Related to latent heat:Latent heat of fusion,Latent heat of vaporization latent heat n. The quantity of heat absorbed or released by a substance undergoing a change of state, such as ice changing to water or water to steam, at constant temperature and pressure. Also calledheat of transformatio...
The meaning of LATENT HEAT is heat given off or absorbed in a process (such as fusion or vaporization) other than a change of temperature.
The latent heat of fusion and heat capacities of paraffin wax are important parameters in design and calculation of thermal energy storage system. A similar definition holds good for latent heat of vaporization. The latent heat of vaporization of water in rough rice is a basic parameter in grain...

We report the calculated results of the latent heat of fusion Δμ ls and the melting temperature T m as a function of cluster size. 给出了团簇熔化潜热和熔点随团簇尺寸的变化关系 ,表明团簇熔化潜热和熔点强烈依赖于团簇的原子数 。4) latent heat of vaporization 汽化潜热 1. Development of mea...
The amount of energy it takes to melt or boil a certain amount of material is called a latent heat. Latent Heat For water, the latent heat of fusion (heat needed to melt ice to water) is 79.7 cal/gm. For water, the latent heat of vaporization (heat needed to boil water) is 540 ...
