04.05.2010· As graphite has a giant lattice structure, it is very hard to break apart. Therefore, high temperatures are required to break these strong bonds to turn it into a liquid state. Thus the melting

Why does graphite have a high melting …

16.01.2019· Now melting is essentially turning a highly ordered state of molecules to a disorderly one. That comes at an expense of energy. In this case, since the constituent molecules of graphite are held together by a strong covalent force, a high amount of energy is needed to weaken that bond. That explains graphite''s high melting point.

Graphite – Structure, Properties and Types

Graphite is the only non-metal that conducts electricity. This is due to the delocalized electron. Graphite is really tough to melt. It does not have a melting point at atmospheric pressure. Most of the graphite used today is manufactured from coal in the electric furnace and not mined. Pencil manufacturing is one of the important uses of graphite.

Why does graphite conduct electricity? - BBC …

19.12.2020· Why does graphite have a high melting point? Both diamonds and graphite have extremely high melting points – both above 3000 degrees Celcius. As you might have guessed, this is due to the strong covalent bonds between their atoms. “When you’re melting something, you’re increasing the distance between atoms…

NaOH has a high melting point and …

NaOH has a high melting point and conducts electricity in solution. H2O has a low melting point and does not conduct electricity. Explain, using the structure of each, why this is the case.

Melting point/boiling point explanation Very high to due all the Explain why Hard, as each carbon atom is covalently bonded to 4 other carbons atoms. Soft and slippery – the layers Graphite conducts electricity, but diamond does not. Explain why.

Why Does Graphite Conduct Electricity? - …

27.03.2020· Graphite conducts electricity because it possesses delocalized electrons in its structure. The honeyco layout of the stacked carbon atoms of graphite leaves a single electron unbound in each hexagon. Each of these electrons is free to move within the structure, enabling electrical conduction.
