Melting Point |
||||||
|
Melting point is the temperature at which a solid, when heated, changes to a
liquid. This temperature is also the freezing point, since a liquid can change phase to a
solid. The proper terminology depends on the direction of the phase change. If a substance
has been transported at a temperature that maintains a solid phase, then a change in
temperature may cause the solid to melt. A particular substance may exhibit totally different properties depending on phase. One phase could be inert while the other is highly reactive. Thus, it is imperative to recognize the possibility of a substance changing phase due to changes in the ambient temperature. |
