  2. Table 1: Viscosity of Selected Fluids and Materials VISCOSITY VALUES Fluid/Material Temperature (C) Viscosity (Pa-s;Pascal-seconds =Newton-seconds/m2)* Air 20 1.8  10-5 Water 20 1.0  10-3 Honey 20 1.6 Flowing hot lava(Hawaiian volcano) ~ 1150 ~ 80 Glass ~ 20 ~ 1012 Ice 0 ~ 1012 Rock Salt 20 ~ 1014 Shallow mantle ~ 1000 ~ 1023-1024 Asthenosphere ~ 1300 ~ 1019-1020 Deep mantle > 1500 ~ 1021-1022 *Viscosity is often given in units of Poise; 10 Poise = 1 Pa-s.
