Melting Point
What is Melting Point?
The melting point is the temperature at which a solid converts to a liquid at a given pressure (usually 1 atm). At the melting point, solid and liquid phases are in dynamic equilibrium and the temperature remains constant until all the solid has melted. Melting points are used to identify and assess the purity of substances — impurities generally lower and broaden the melting point range.
