Melting Point (mp)

Definition - What does Melting Point (mp) mean?

Melting Point, also known as liquefaction point, is the temperature at which a solid substance changes into liquid state. Solid as well as liquid phases exist in equilibrium in the Melting point. When a solid substance is heated, its temperature increases until its melting point is reached. Further heating converts it into the liquid state.

Petropedia explains Melting Point (mp)

There are many laboratory techniques available for determining the Melting Point of a substance, out of which a common technique is by using “Kofler Bench” with samples for calibrations. It is a metal strip having a temperature scale ranging from room temperature to 300 degree Celsius. The substance to be tested for its Melting Point is placed on this metal strip and its thermal behavior at that particular temperature is recorded. A calorimeter is used to calibrate the information on Melting Point along with the enthalpy of fusion.
