Question

define lubricants? plz give answer fast ​

Answer 1

Answer: a substance, as oil or grease, for lessening friction, especially in the working parts of a mechanism. There are three different types of lubrication: boundary, mixed and full film. Each type is different, but they all rely on a lubricant and the additives within the oils to protect against wear. Full-film lubrication can be broken down into two forms: hydrodynamic and elastohydrodynamic. 1 : a substance (such as grease) capable of reducing friction, heat, and wear when introduced as a film between solid surfaces. 2 : something that lessens or prevents friction or difficulty a social lubricant.

A lubricant is a substance, usually organic, introduced to reduce friction between surfaces in mutual contact, which ultimately reduces the heat generated when the surfaces move. The property of reducing friction is known as lubricity. In addition to industrial applications, lubricants are used for many other purposes.
