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.
Graphite is a dark gray to black, very soft, shiny metallic mineral with a distinctive greasy feeling. One of the Earthâs softest minerals, graphite will easily leave marks on paper, which is why it is used for fine artist pencils.
