why does calcium fluoride have a high melting point - …
Both are diatomic with simple molecular structures. Both have van Der Waals forces of attraction between molecules but since Br2 is larger than F2 so has more electrons, these forces are stronger in Br2 so the melting point is greater for Br2 than F2. (Original post by Endany keroi)

Why is the melting point of magnesium less than that of …
Excellent question. I’ll try to answer it. You see Calcium and Magnesium are group two elements. The Group 2 elements are all metals with metallic bonding, so you expect their melting points to be high. In metallic bonding, metal ions in a meta
CalcTool: Boiling points calculator
Substance properties online calculation: Boiling points - Estimation at required temperatures and pressures. The vapor pressure of most liquids has a fairly predictable temperature-dependence, so from one boiling point measurement it is possible to give a good estimation of the boiling point at other pressures (or boiling pressure at other temperatures).
