Rubber begins to melt at approximately 180 degrees Celsius. At low temperatures, around 5 C to 6 C, there is a risk that rubber hardens because of crystallization. The optimum temperature for rubber is 20 C.
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).
