Measured values span several orders of magnitude. Of all fluids, gases have the lowest viscosities, and thick liquids have the highest. The values listed in this article are representative estimates only, as they do not account for measurement uncertainties, variability in material definitions, or non-Newtonian behavior.

The activation energy Q takes a different value depending on whether the high or low temperature limit is being considered: it changes from a high value Q H at low temperatures (in the glassy state) to a low value Q L at high temperatures (in the liquid state). Common logarithm of viscosity against temperature for B 2 O 3, showing two regimes

a table showing ranges of values of hydraulic conductivity and permeability for various geological materials. Values are for typical fresh groundwater conditions — using standard values of viscosity and specific gravity for water at 20 °C and 1 atm. See the similar table derived from the same source for intrinsic permeability values. [13]

These groups may contain only two-fold axes, mirror planes, and/or an inversion center. These are the crystallographic point groups 1 and 1 (triclinic crystal system), 2, m, and 2 / m , and 222, 2 / m 2 / m 2 / m , and mm2 (orthorhombic). (The short form of 2 / m 2 / m 2 / m is mmm.)
