Hot liquids flow more easily than cold liquids. Give the reason.

(N/A) The viscosity of a liquid is defined by its coefficient of viscosity,denoted by $\eta$.
As the temperature of a liquid increases,the intermolecular forces of attraction decrease.
Consequently,the coefficient of viscosity $\eta$ decreases for hot liquids.
Since the viscous drag force between consecutive layers is given by $F = -\eta A \frac{dv}{dx}$,a lower value of $\eta$ results in a smaller viscous force.
Therefore,hot liquids experience less internal resistance and flow more easily than cold liquids.
