The melting point is also called the liquefaction point or the fusion point.
Under ordinary conditions they are the same 'point'. For example, water just freezes and it just melts at zero degrees centigrade. The difference between the two states is not temperature, but the heat of fusion. When the heat of fusion is removed from water at zero degrees, it will freeze. When the heat of fusion is added to ice at zero degrees, it will melt.
The melting point of Magnesium is about 650 deg C.
A solid becomes a liquid when it temperature has reached its Melting Point (also called it Point of Fusion.)
The heat needed to melt one gram of a solid at its melting point depends on the heat of fusion value of the solid. To melt one gram of ice, for example, would require 334 J.
because they their point of fusion are low or upon the point of fusion of the water.
The melting point equation for a substance is typically represented as Hfusion TmSfusion, where Hfusion is the enthalpy of fusion, Tm is the melting point temperature, and Sfusion is the entropy of fusion.
The melting point is also called the liquefaction point or the fusion point.
Because of the heat of fusion the ice is now water

The melting point of Magnesium is about 650 deg C.
This is called the melting point (symbol Tm).The melting point is different for different elements, compounds, and materials. Some solids, wax for example, has a relatively low melting point, while the melting point of some alloys, such as steel, is very high. The melting point of ice is the freezing point of water, subject to the enthalpy of fusion (the heat of fusion).
