Asked by zrajani | 29th Aug, 2011, 12:00: AM

Expert Answer:

A lubricant is a substance introduced to reduce friction between moving surfaces
A coolant is a fluid which flows through a device to prevent its overheating, transferring the heat produced by the device to other devices that use or dissipate it. An ideal coolant has high thermal capacity, low viscosity, is low-cost, non-toxic, and chemically inert, neither causing nor promoting corrosion of the cooling system
