Melting \Melt"ing\, n. Liquefaction; the act of causing (something) to melt, or the process of becoming melted.
Melting point (Chem.), the degree of temperature at which a solid substance melts or fuses; as, the melting point of ice is 0[deg] Centigrade or 32[deg] Fahr., that of urea is 132[deg] Centigrade. Pressure affects the melting point somewhat, and if not specified the melting point is usually taken to be at atmospheric pressure.
Wiktionary
n. (context chemistry English) The temperature at which the solid and liquid phases of a substance are in equilibrium; it is relatively insensitive to changes in pressure
WordNet
n. the temperature below which a liquid turns into a solid [syn: freezing point]
Wikipedia
The melting point (or, rarely, liquefaction point) of a solid is the temperature at which it changes state from solid to liquid at atmospheric pressure. At the melting point the solid and liquid phase exist in equilibrium. The melting point of a substance depends on pressure and is usually specified at standard pressure. When considered as the temperature of the reverse change from liquid to solid, it is referred to as the freezing point or crystallization point. Because of the ability of some substances to supercool, the freezing point is not considered as a characteristic property of a substance. When the "characteristic freezing point" of a substance is determined, in fact the actual methodology is almost always "the principle of observing the disappearance rather than the formation of ice", that is, the melting point.
