The viscosity of water is 1.0020 millipascal seconds at 20°C. The viscosity of water, and other substances, can change with a difference in temperature. Water has low viscosity compared to other fluids.
When a substance is viscous, it is said to be "thick," meaning it is difficult to move through the fluid. An example of a substance with high viscosity is honey. Others are so viscous that they almost seem solid, like butter or margarine. These mentioned substances flow easier at higher temperatures; that means they become less viscous. Most common fluids have a constant viscosity regardless of force applied. These fluids are called Newtonian fluids.Learn More
Measure the centipoise, or cP, of a fluid using a viscometer. Centipoise is a unit of viscosity in the centimeter gram second system; in the International System of Units the pascal second replaces centipoise.Full Answer >
Most often, thicker liquids take longer to boil. Viscosity and boiling point are both physical properties that are determined by intermolecular forces. Although viscosity and boiling point do not directly affect each other, there is a correlation based on the strength of these intermolecular forces.Full Answer >
Sterile and distilled water are both essentially pure H2O, but each is used for different purposes. Distilled water is distributed for use in laboratories and for ordinary consumption. Sterile water is used in the medical community as a wound cleanser or an intravenous fluid.Full Answer >
Silicon dioxide, the primary component in sand, forms in large crystalline structures, which are held together by covalent bonds. These bonds require more energy to break than the polarity of water is able to supply. While water is able to dissolve a minute amount of silicon dioxide, natural water supplies are at the saturation point and unable to dissolve any more sand.Full Answer >
