WebApr 30, 2024 · In general, the viscosity of a simple liquid decreases with increasing temperature. While liquids get runnier as they get hotter, gases get thicker. (If one can imagine a “thick” gas.) The viscosity of gases increases as temperature increases and is approximately proportional to the square root of temperature. WebStating an oil’s viscosity is meaningless unless the temperature at which the viscosity was measured is defined. Typically, the viscosity is reported at one of two temperatures, either 40°C (100°F) or 100°C (212°F). For most …
