Melting point, freezing point, and melting point of solids and liquids

Solids in general to a liquid when heated. Will become solid when cooled or frozen. The change from solid to liquid form so-called melt or fuse. Change from liquid to solid form called ice. Water freezes at 0 degrees C. The temperature at the time of freeze-called freezing. Gold will melt at a temperature of 1,530 degrees C, the silver will melt at a temperature of 960 degrees C. The wax will melt at a temperature of 54 degrees C. The melting point, freezing point, and the melting point of an object is different.

All the liquid will evaporate when heated. Liquid evaporation time is not the same. There are fast and some are slow. To accelerate the evaporation process can be done by:
a. Extending surface drying clothes, for example by stretching out to dry
b. Blew surface of the liquid, for example hot water blown in order to quickly cool
c. Adding heat eg direct drying in the sun that dries quickly.
