Melting Point: Everyday and Scientific Definitions. Now that we know something about phase diagrams, it will make more sense why scientists define melting point the way they do. First, in everyday terms, the melting point is the temperature at which a substance melts or freezes.
Water usually melts and freezes at 32Â°F (0Â°C) and boils at 212Â°F (100Â°C). The familiarity of water may make the melting points of other substances extreme by comparison. For example, the temperature at which carbon melts is 6,422Â°F (3,550Â°C), while mercury melts at -37.97Â°F (-38.87Â°C).
