The viscosity of liquid decreases with increasing temperature because on increasing temperature the kinetic energy of molecules also increases. Due to more kinetic energy, the flow of molecules increases. Arrhenius and Geezman gave equation on the basis of experiments which shows the effect of temperature on viscosity.
n = Ae -Ea/RT
\(log\ \frac{n_1}{n_2} = \frac{Ea}{2.303R}\left[\frac{T_2 - T_1}{T_1T_2}\right]\)
