Why does the viscosity of liquids decrease with temperature? The increase in temperature causes the kinetic or thermal energy to increase and the molecules become more mobile. The attractive binding energy is reduced and therefore the viscosity is reduced. How does viscosity of liquids vary with temperature? The viscosity of liquids decreases rapidly with an […]
