Question

what are lubricants?give two examples ??..​

Answer 1

Explanation:

A lubricant is a substance which introduced to reduce friction between surfaces in mutual contact, which ultimately reduces the heat generated when the surfaces move. For example - motor oil, friction modifier, friction additive, gel, silicons, flourocarbons, ect.

Answer 2

$\huge{\underline{\mathfrak{\red{✯A}\pink{N}\green{S}\blue{W}\purple{E}\orange{R}}}}$

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. ... In addition to industrial applications, lubricants are used for many other purposes.

Explanation:

Common examples of internal lubricants include fatty alcohols, esters (low esterification), and EVA wax. External lubricants provide metal release and help reduce process temperature. Common examples of external lubricants include PE waxes, paraffin, metal soaps, esters (high esterification), amides, and fatty acids.

I hope it will be help you ❤️❤️❤️
