For 10 points, name this resistance to flow of substances, which can be measured in units of poise or stokes.
This property increases with temperature in gases due to an increase of friction between molecules, while in liquids it decreases with an increase in temperature. Generally calculated by dividing stress to shear strain, the absolute variety can be divided by mass density to derive the kinematic variety of this property, first discovered by Isaac Newton.
