1.37 Explain, in terms of structure and bonding, why graphite is used to make electrodes and as a lubricant, whereas diamond is used in cutting ​​​​ tools

Question 1

What is a use of graphite?

Answer 1

Graphite is used as electrodes because it can conduct electricity, unlike diamond.

Question 2
