Capillary Action

Viscosity of a fluid, also called the coefficient of viscosity, absolute viscosity, or dynamic viscosity, is a measure of its resistance to flow. It is expressed as the ratio of the tangential shearing stresses between flow layers to the rate of change of velocity with depth

Capillary action decreases with increase in temperature. Its temperature variation is small and insignificant in most problems.
