Question

what are lubricants?How do they work​

Answer 1

Answer:

A lubricant is a substance that helps to reduce friction between surfaces in mutual contact, which ultimately reduces the heat generated when the surfaces move. It may also have the function of transmitting forces, transporting foreign particles, or heating or cooling the surfaces. Lubricants aim at reducing friction between moving pieces and at reducing passive resistance of the stationary parts. They are produced by refining heavy fractions of crude oil (remaining crude oil parts after refining hydrocarbons such as gas, fuel oil or kerosene)- it will helpful for you.

Answer:
A lubricant is a substance that forms a thin layer between the two surfaces in contact. Eg- Talcum powder, oil, grease etc
