  2. Non-Newtonian fluid - Wikipedia

    en.wikipedia.org/wiki/Non-Newtonian_fluid

    The sudden application of force—by stabbing the surface with a finger, for example, or rapidly inverting the container holding it—causes the fluid to behave like a solid rather than a liquid. This is the "shear thickening" property of this non-Newtonian fluid. More gentle treatment, such as slowly inserting a spoon, will leave it in its ...

  3. Liquid - Wikipedia

    en.wikipedia.org/wiki/Liquid

    A liquid is a nearly incompressible fluid that conforms to the shape of its container but retains a nearly constant volume independent of pressure. It is one of the four fundamental states of matter (the others being solid, gas, and plasma), and is the only state with a definite volume but no fixed shape.

  4. Suspension (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Suspension_(chemistry)

    When light is sent through the sample, it is back scattered by the particles. The backscattering intensity is directly proportional to the size and volume fraction of the dispersed phase. Therefore, local changes in concentration ( sedimentation ) and global changes in size ( flocculation , aggregation ) are detected and monitored.

    en.wikipedia.org/wiki/List_of_states_of_matter

    Liquid crystal: Properties intermediate between liquids and crystals. Generally, able to flow like a liquid but exhibiting long-range orientational order. Supercritical fluid: A fluid with properties intermediate of liquids and gasses. At sufficiently high temperatures and pressures, the distinction between liquid and gas disappears, resulting ...

  6. State of matter - Wikipedia

    en.wikipedia.org/wiki/State_of_matter

    Liquid crystal states have properties intermediate between mobile liquids and ordered solids. Generally, they are able to flow like a liquid, but exhibiting long-range order. For example, the nematic phase consists of long rod-like molecules such as para-azoxyanisole, which is nematic in the temperature range 118–136 °C (244–277 °F). [10]

  7. Colloid - Wikipedia

    en.wikipedia.org/wiki/Colloid

    A colloid is a mixture in which one substance consisting of microscopically dispersed insoluble particles is suspended throughout another substance. Some definitions specify that the particles must be dispersed in a liquid, [1] while others extend the definition to include substances like aerosols and gels.

    Megan Liu, lead study author and science and policy manager at Toxic-Free Future, tells Yahoo Life that this was a “minor point” in the study. “We feel bad that this happened,” she adds.

  9. Aqueous solution - Wikipedia

    en.wikipedia.org/wiki/Aqueous_solution

    Substances that are hydrophobic ('water-fearing') do not dissolve well in water, whereas those that are hydrophilic ('water-friendly') do. An example of a hydrophilic substance is sodium chloride. In an aqueous solution the hydrogen ions (H +) and hydroxide ions (OH −) are in Arrhenius balance ([H +] [OH −] = K w = 1 x 10 −14 at 298 K).
