THE PHYSICAL PROPERTIES OF GRAPHITE.
Has a high melting point, similar to that of diamond. In order to melt graphite, it isn’t enough to loosen one sheet from another.
You have to break the covalent bonding throughout the whole structure.
Has a soft, slippery feel, and is used in pencils and as a dry lubricant for things like locks.
You can think of graphite rather like a pack of cards – each card is strong, but the cards will slide over each other, or even fall off the pack altogether.
