Web5 mrt. 2024 · Measurement of a solid compound's melting point is a standard practice in the organic chemistry laboratory. The melting point is the temperature where the solid-liquid phase change occurs. In some reference books it is listed as a single value (e.g. 98˚C), but in chemical catalogs it is more often listed as a range of values (e.g. 96-98˚C). WebMelting is simply a phase change in which water molecules move from a crystalline structure to a less ordered structure in which the molecules can move about more freely. 4 Rick Bagnall Studied Chemistry Education at Purdue University Author has 1.9K answers and 882.8K answer views 3 y Related Why is melting an endothermic process? esquire theater st louis
