Why Viscosity Decreases with Increase of Temperature in Liquids?
In liquids, viscosity typically decreases with an increase in temperature due to changes in molecular behavior. As temperature rises, the kinetic energy of liquid molecules increases, causing them to move more rapidly. This increased motion disrupts the cohesive forces between molecules, such as hydrogen bonding or van der Waals forces, which contribute to viscosity by impeding the flow of the liquid. As these intermolecular forces weaken with higher temperatures, the liquid molecules can move more freely past each other, resulting in lower resistance to flow and a decrease in viscosity. Additionally, the higher thermal energy at elevated temperatures can also lead to increased molecular spacing and decreased density, further reducing viscosity. Overall, the combination of weakened intermolecular forces and increased molecular motion accounts for the observed decrease in viscosity with temperature in liquids.
How to Calculate Dynamic Viscosity of Liquids?
Dynamic Viscosity of Liquids calculator uses Dynamic Viscosity Fluid = Experimental Constant 'A'*e^((Experimental Constant 'B')/(Absolute Temperature of Fluid)) to calculate the Dynamic Viscosity Fluid, Dynamic Viscosity of Liquids is a property that relates to its resistance to flow. Liquids with higher viscosity flow slower at a given temperature. For many liquids, the temperature dependence of viscosity can be represented reaspnably well by the Arrhenius equation. Dynamic Viscosity Fluid is denoted by μ_{} symbol.
