The dual coding theory proposed by Paivio attempts to give equal weight to verbal and non-verbal processing. Paivio (1986) states: Human cognition is unique in that it has become specialized for dealing simultaneously with language and with nonverbal objects and events.
Therefore, high temperatures are required to break these strong bonds to turn it into a liquid state â¦ . Thus the melting point of graphite is high, same goes for diamonds. Even though it is a covalently bonded compound, these 2 examples are the only ones that have high melting points. The melting point of graphite is 3500 c and 6332 f, specific gravity is 2.25, pounds per cubic inch is .812, 21 people found this useful.
The melting point is the temperature at which a solid will turn into a liquid, and the boiling point is the temperature at which a liquid will turn into a gas. + 19 others found this useful. Areta Mansfield.Edit.ince the bonds are strong â¦ (covalent, network), diamond has a very high melting point and boiling point. Iodine does not have three dimensional network and hence has very low melting/ boiling point. It fact, it will sublime at room temperature.
