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.
Best Answer: It depends on the rock, but typically about 600 C (1100 F) to 1200 C (2200 F). Quartz or quartz rich rocks have the lowest melting point, and basaltic rocks have the highest melting points. So at 1500 F, it is difficult to tell. Quartz can become explosive, but this occurs at much higher temperatures and pressures, such as in volcanic episodes.
