In most cases an increase in temperature will lower the viscosity of a material, but there are exceptions, like sulfur, which form polymers.
Usually the increase in temperature decreases the viscosity of a liquid due to weakness of intermolecular attractions but some mixtures show an increase in viscosity with the rise of temperature as egg (proteins).
Increasing the density of a liquid typically results in an increase in viscosity. This is because higher density usually means more intermolecular interactions and greater resistance to flow. In other words, the molecules are packed more tightly, leading to stronger forces between them, which makes it more difficult for the liquid to flow.
Increasing the temperature of a liquid decreases its viscosity. This is because heating the liquid causes the molecules to move more easily past each other, resulting in a decrease in the liquid's resistance to flow.
Temperature measures the speed of random thermal motion on the atomic and molecular level. When sub-microscopic particles are moving faster, the liquid as a whole will be more fluid and less viscous.
Factors that can affect the rate of speed of a liquid include temperature (higher temperature typically increases speed), viscosity (higher viscosity slows down the liquid), pressure (increased pressure can increase speed), and the presence of any obstacles or barriers in the liquid's path.
viscosity decreases with increase in temperature

Viscosity is the resistance of a liquid to flow. When temperature decreases Viscosity generally increases. Viscosity generally decreases when the temperature increases.

Liquid's viscocity depends on temperature. As a rule, viscosity drops with the increase of temperature.
As the temperature increases, the viscosity of the liquid will decrease.

Temperature, concentration, sometimes also internal fluid velocity. Moreover density, type of liquid, surface where it flows, viscous drag.

HSP With increase in temp.the viscosity of liquids decreases,thereby increasing the flow rate and vice versa.The decrease in viscosity with rising temp.is due to the fact that the intermolecular attraction decreases and the cohesive forces increases. This does not apply with water
