Meaning of Melting Point

what is melting point:

Melts as melting point is called, in chemistry, the temperature to which a substance passes from solid to liquid, i.e.. Melting point varies with each substance, then that is considered as one of the characteristics of the elements and a physical constant. Water, for example, reaches its melting point at 0° C atmosphere pressure.

Melting point, moreover, is constant and unchanging when the substance is subjected to normal pressure, because, unlike the boiling point, the melting point is not particularly affected by the pressure.

Meaning of Melting Point 1

Melting point is also used in chemistry as an indicator of the level of purity of a substance, being that the higher purity, higher melting point and smaller scale of variation, as opposed to the impure substance, where you register a melting point of more low, but a scale wider temperature variation.

Melting point and boiling point

Melting point is the temperature which occurs in the transition of a substance from the solid state to liquid when subjected to an elevation of its temperature. Moreover, the boiling point is the temperature which occurs throughout a substance from the liquid state to the gaseous.

Meaning of Melting Point 2

In this sense, the temperature at which boiling occurs will always be higher than the melting point.

Point of fusion and solidification point

In the majority of the elements, the melting point coincides with the point of solidification. I.e., the temperature at which a substance subjected to a falling temperature, passes from liquid to solid (solidification) State is equal to the temperature at which a substance passes from solid to liquid (melting) when it is subjected to a temperature up.
