प्रश्न
How does graphite act as a lubricant?
उत्तर
Graphite has a hexagonal structure and weak van der Waals force between the layers of the carbon atoms in its crystal. Due to this weak force, the layers of carbon atoms in graphite can slide over one another, making graphite slippery in nature and capable of acting as a lubricant.
