Use the following two viscosity values for liquid water:

η = 1.8 x 10-3 Ns/m2 at 0 o C

η = 2.8 x 10-4 Ns/m2 at 100 o C

At what temperature do you need a lesser force to pull a given glass slide with a given speed v though the water?

• Physics -

viscosity is a measure of the force it takes to move through the liquid

the lower value requires less force.
