Question

grafite is used as a lubricant give reason

Answer 1

Graphite is the mineral form of carbon. Veins of graphite occur in limestone due the presence of organic materials. Graphite is a soft mineral and occurs in either lump or flake form. Graphite is the only non-metal element that is a good conductor of electricity. Crystal structures rarely occur and easily break down. This is the reason for the material’s greasy feeling despite being a dry lubricant.

Answer 2

These electrons can move through thegraphite, carrying charge from place to place and allowing graphite to conduct electricity... Graphite is used as a lubricant due to its slippery nature.Graphite has layers of carbon atoms, with weak forces, residing in between its layers because of which it is quite slippery.
