Graphite occurs in metamorphic rocks as a result of the reduction of sedimentary carbon compounds during metamorphism. It also occurs in igneous rocks and in meteorites. Minerals associated with graphite include quartz, calcite, micas and tourmaline. The principal export sources of mined graphite are in order of tonnage: China, Mexico, Canada, Brazil, and Madagascar. WebThe state of a substance at a given temperature can be predicted if its melting point and boiling point are known. The table summarises how to work this out. Question The melting point...

WebMelting point: 0 degrees C At higher altitudes, air pressure is lower. When the pressure is lower, it takes less energy to bring water to a boil, less energy means less heat so water boils at a lower temperature at a higher altitude. In freezing and melting points, there is a very slight difference but it is unidentifiable in this experiment. Web11 rows · Melting point of Graphite is 3600 °C. Note that, these points are associated with the ... WebGraphene is a single-atom thick layer of graphite with strong covalent bonds between each carbon atom. The atoms are arranged in hexagons. Its properties include: high melting and boiling... sharing their effort
