Answer:
A lubricant can be defined as a substance , like as grease capable of reducing friction , heat, and wear when introduced as a film between solid surfaces . it is usually organic , introduced reduce friction between surfaces in mutual contact , which eventually reduces the heat generated when the surfaces move. lubricants may also have the function of transporting foreign particals, transmitting forces, or heating or cooling the surfaces.
