How does the viscosity of oil vary with temperature?

i need help for a project on this topic.





How does the viscosity of oil vary in temperature?





how can u find the viscosity adn what do you sue to measure the temperature?





WHY does it vary??





if you can, please list some sources from the internet.





thank youHow does the viscosity of oil vary with temperature?
viscosity raise when the temperature goes down.





it varies because molecules of the fluids, when temperature is low, have less energy so they can't move very much. So the fluids seems to be harder. When the temperature is high, molecules have more energy and they can move more easily, so the the fluids is more smooth.





there is some table that show the relation between viscosity and temperature. Or you can use some empiric equation.How does the viscosity of oil vary with temperature?
I think (this is just a guess) that the viscosity varies because when the temperature drops, the molecules slow down and are less willing to move as to when they are heated up and the molecules are bouncing around like crazy, thus, sliding along easily. This is just me thinking and you may want to research this theory more. Hope it was some help! =)
