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?
resistance of a fluid to flow. This resistance acts against the motion of any solid object through the fluid and also against motion of the fluid itself past stationary obstacles. Viscosity also acts internally on the fluid between slower and faster moving adjacent layers.Does temperature affect the viscosity of oil? If so how?
The thermal energy in the fluid is higher when it's at a higher temperature (duh!). The molecules are more excited in this state of higher temperature (thermal energy) and have less resistance to flow/movement.
Yes. If your motor oil is at 0 degrees Fahrenheit, your car will barely start, if at all. When the Temperature is 50 degrees F. , it will start easily.
