对熔化和凝固的辨别理解物质从固态变成液态叫做熔化,熔化吸热,如冰变成水.熔化和溶化的区别:前者表示物质由固态变成液态;后者表示一些溶质溶解在溶剂中的过程(化学概念),如盐溶于水变成盐水.熔化和溶化不要混淆. Differentiation between melting and solidification Understanding that a substance changes from a solid state to a liquid state is called melting, and a melting endotherm, such as ice, changes to water. The difference between melting and dissolving is that the former means that the substance changes from a solid to a liquid state and the latter indicates that some solute is dissolved in a solvent (Chemical concept), such as salt dissolved in water into brine, do not mix and melt.
