WebHF's high boiling point is due to hydrogen bonding which none of the other HX molecules show. The general trend is that BP increase as molecules get heavier due to more … Web5.1.4 Boiling Point Elevation. As described in the chapter on liquids and solids, the boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since the vapor pressure of a solution is lowered due to the presence of nonvolatile solutes, it stands to reason that the solution’s boiling point will … WebSilicon has high melting and boiling points because it is a giant covalent structure. You have to break strong covalent bonds before it will melt or boil. Because you are talking about a different type of bond, it isn't profitable to try to directly compare silicon's melting and boiling points with aluminium's.

The temperature at which solid changes its state to liquid at atmospheric pressure is called the melting point of that liquid. This is the point at which both liquid and solid phase exists at equilibrium. The melting point of the substance also varies with pressure and is specified at standard pressure.
