Does temperature affect the viscosity of oil?


Why is it thinner when it's hot.. and vice versa.


Explain what happens to the particles etc.


THANKS!!Does temperature affect the viscosity of oil? If so how?
If 渭 is the dynamic viscosity of the liquid or gas and T is the temperature, the following holds true:





Gases:


渭 ~ T^(3/4)


Viscosity increases as temperature increases.





Liquids:


渭 ~ (A - B ln(T))


Viscosity decreases as temperature increases.





Oil is a liquid, so its viscosity will decreases as the temperature goes up. This is due the more energetic motion of the oil molecules, making bonds between molecules harder to form. Fewer bonds means the molecules slide past each other more easily.Does temperature affect the viscosity of oil? If so how?
I have read a lot of your answers which would seem true. Sorry they are not totally correct. ever hear of multi grade oils like 5W40 this motor oil is thinner when cold and thicker when hot.. Viscosity is the molecular size of the oil particles. when cold it constricts and when hot it expands in size.
It most definitely does. Hydrogen bonds between the oil molecules are more easily broken if there is thermal energy, i.e. the oil is hot.
I would assume that it'd be thinner when it's hot and thicker when it's cold, just because that's how temperature effects most other mediums.
It's how temperature affects liquids, gases and solids. As the temperature drops the molecules become less active and crowd closer together. Add heat and they vibrate-become more active- and move farther apart.
