Viscosities at or near standard conditions -- Liquids
Viscosity is a material property which describes the resistance of a fluid to shearing flows. It
corresponds roughly to the intuitive notion of a fluid's 'thickness'. For instance, honey has
a much higher viscosity than water. Viscosity is measured using a viscometer. Measured values span several orders
of magnitude. Of all fluids, gases have the lowest viscosities, and thick liquids 
have the highest.
