Which of the following is not a lubricant
Oil
Water
Grease
Graphite
Pls tell me guys?
Dear student,
1. Water is not a lubricant.
2. Oil is used as lubricant.
3. Grease is a semi solid lubricant consists of soap emulsified with minerals or vegetable oils.
4.Graphite consists of layers of bonded carbon atoms. Each layer is made up of hexagonally bonded carbon atoms.The forces of attraction between these layers are weak van der Waals forces.Due to this, these layers can slide over each other and thus graphite can be use as lubricant.
Regards
