Question

Does temperature affect the viscosity of oil? If so,how? How can this change be measured?

Materials

-60mL of oil

-graduated cylinder

-timer

-cup woth hole on the bottom

-beaker

-stand(?)

-thermometer

-box with full of ice and water

and....

-us!

During the experiment...

In this experiment we tested how the temperature of the vegetable oil affect the viscosity of the oil. We made the oil into 3types, 20 degrees, 9 degrees, and 52degrees. we have about 60mL of vegetable oil in the graduated cylinder, and we pour all of them into the plastic cup with the hole on the bottom. Then we measured the time that the oil fall into the beaker, when the oil reaches to 50mL, we stopped. when the oil's temperature was 9 degrees, the flow rate was low and when the oil's temperature were 52 degrees, the flow rate was high. So if the oil's temperature is low, it's flowrate is slow, and if the oil's temperature is high, the flow rate is fast.

*Flowrate=volume/time
