The melting point of a substance is the temperature at which it melts when you heat it. the temperature at which a solid substance becomes a liquid. Temperature at which the solid and liquid states of a pure substance can exist in equilibrium. As heat is applied to a solid, its temperature increases until it reaches the melting point. At this temperature, additional heat converts the solid into a liquid without a change in temperature. The melting point of solid water (ice) is 32°F (0°C). Though the melting point of a solid is generally considered to be the same as the freezing point of the corresponding liquid, they may differ because a liquid may freeze into different crystal systems and impurities can lower the freezing point
The temperature at which a solid substance undergoes fusion, i e melts, changes from solid to liquid form All substances have their characteristic melting points For very pure substances the temperature range over which the process of fusion occurs is very small The melting point of a pure crystalline solid is a process of pressure It increases with increasing pressure for most substances However in the case of ice (and a few other substances) the melting point decreases with increasing pressure Under a pressure of one standard atmosphere, the melting point of pure ice is the same as the ice point, that is 0°C or 32°F
The temperature at which a solid changes its phase to a liquid This temperature is also the freezing point depending on the direction of the change For mixtures, a melting point range may be given
The temperature at which a solid substance becomes a liquid, or at which a liquid substance solidifies Listed in Celsius degrees on the ChemFinder WebServer Assumed to be at standard pressure unless otherwise indicated Sometimes present as a temperature range if an exact value is unavailable Sometimes accompanied by a note such as dec (decomposes) or subl (sublimes)
The melting point is the temperature at which a solid material becomes a liquid The freezing point is the temperature at which a liquid material becomes a solid Usually one value or the other is given on an MSDS It is important to know the melting or freezing point for storage or handling purposes For example, a melted or frozen material may burst a container As well, a change of physical state could alter the hazards of the material
The temperature at which the last crystal of ice disappears during warming For example, the melting point of water is 0°C and for a 10% solution of glycerol -2 1°C
The temperature at which solid and liquid forms of a substance are in equilibrium In common usage, the melting point is taken as the temperature at which the liquid first forms in a small sample as its temperature is increased gradually
The temperature at which a pure metal, compound or eutectic changes form solid to liquid; the temperature at which the liquid and the solid are in equilibrium
Melting point is the temperature at which the solid and liquid phases of a substance are in equilibrium at a specified pressure (normally taken to be atmospheric unless stated otherwise)
