In condensed matter physics and physical chemistry, the terms viscous liquid, supercooled liquid, and glass forming liquid are often used interchangeably to designate liquids that are at the same time highly viscous (see Viscosity of amorphous materials), can be or are supercooled, and able to form a glass.
Tar is a dark brown or black viscous liquid of hydrocarbons and free carbon, obtained from a wide variety of organic materials through destructive distillation. Tar can be produced from coal, wood, petroleum, or peat. [1] Mineral products resembling tar can be produced from fossil hydrocarbons, such as petroleum.
A sticky, black and highly viscous liquid or semi-solid that is present in most crude petroleums and in some natural deposits. assembled gem. Also called a composite gem. asthenosphere A region of the Earth's outer shell beneath the lithosphere. The asthenosphere is of indeterminate thickness and behaves plastically. augite
Bitumen (UK: / ˈ b ɪ tʃ ʊ m ɪ n / BIH-chuum-in, US: / b ɪ ˈ tj uː m ɪ n, b aɪ-/ bih-TEW-min, by-) [1] is an immensely viscous constituent of petroleum. Depending on its exact composition it can be a sticky, black liquid or an apparently solid mass that behaves as a liquid over very large time scales.

For liquid, the dynamic viscosity is usually in the range of 0.001 to 1 Pascal-second, or 1 to 1000 centiPoise. The density is usually on the order of 1000 kg/m^3, i.e. that of water. Consequently, if a liquid has dynamic viscosity of n centiPoise, and its density is not too different from that of water, then its kinematic viscosity is around n ...
Triethanolamine, or TEOA, is an organic compound with the chemical formula N(CH 2 CH 2 OH) 3.It is a colourless, viscous liquid. It is both a tertiary amine and a triol.A triol is a molecule with three alcohol groups.
Viscosity is a measure of a fluid's rate-dependent resistance to a change in shape or to movement of its neighboring portions relative to one another. [1] For liquids, it corresponds to the informal concept of thickness; for example, syrup has a higher viscosity than water. [2]
