(B) The variation of the viscosity coefficient $(\eta)$ of liquids with temperature $(T)$ is described by the Andrade equation,which is given by the expression: $\eta = A e^{E / R T}$.Here,$A$ is a constant,$E$ is the activation energy for viscous flow,$R$ is the universal gas constant,and $T$ is the absolute temperature.As temperature increases,the viscosity of liquids decreases,which is consistent with the exponential form $\eta = A e^{E / R T}$.
