Explain the Effect of Temperature on Surface Tension and Viscosity

Viscosity and surface tension are two rudimentary properties of the liquid. The layers of the fluid show resistance and that is known as viscosity and the same resistance that is shown by the surface of the liquid against penetration is known as surface tension. As temperature increases, viscosity decreases. In simple terms viscosity refers to the liquid’s resistance to flow, so, with increasing heat, fluid starts to flow more smoothly. As temperature increases, surface tension decreases. Because when temperature increases, molecular thermal activities also increase and as a result of that intermolecular cohesive force decreases and finally surface tension decreases.
