The melting point of Calcium is 839℃ and the boiling point is 1484℃.
Melting point −209.86°C; boiling point −195.8°C
A boiling point is a point on the temperature scale at which a substance begins to boil. A melting point is a point on the temperature scale at which a substance freezes. Melting and boiling points are unique to different types of elements.
Melting and boiling points are important characteristics of materials: they are needed in industry and in laboratory.
During the melting of ice, entropy and enthalpy work together. The increase in entropy (disorder) as solid ice turns into liquid water disrupts the ordered crystal lattice structure. This process requires an input of energy (enthalpy) to break these intermolecular forces holding the ice together.
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.
Impossible to calc any melting or boiling points.

The enthalpy of fusion is the heat energy absorbed or released when a substance changes from solid to liquid at its melting point. The enthalpy of vaporization is the heat energy absorbed or released when a substance changes from liquid to gas at its boiling point.
Melting and boiling are physical changes.
Stoichiometry can be used to calculate the energy absorbed when a mass melts by considering the enthalpy of fusion, which is the amount of energy required to change a substance from solid to liquid at its melting point. By using the molar mass of the substance and the enthalpy of fusion, you can calculate the amount of energy needed to melt a specific mass of the substance.
Melting: -259.14 C Boiling: -252.87 C
Elements have fixed melting and boiling points, while compounds have varying melting and boiling points depending on their composition. Mixtures do not have fixed melting and boiling points, as they are composed of multiple substances which each have their own individual melting and boiling points.
thawing
No boiling is heating and energy is added and melting the solid turns into a liquid.
Melting: 700 C Boiling: 1737 C
