Answer: A substance in liquid or gaseous state which is capable of deforming continuously under the action of shear stress (however small the shear stress may be). A fluid which shows as decrease in apparent viscosity with time. Also, It has shear-thinning characteristics. c.g. Printer’s ink, honey A fluid for which apparent viscosity increases with time.
