  2. Structure of liquids and glasses - Wikipedia

    en.wikipedia.org/wiki/Structure_of_liquids_and...

    The attenuation of the peaks at increasing radial distances from the center indicates the decreasing degree of order from the center particle. This illustrates vividly the absence of "long-range order" in liquids and glasses. At long ranges, g(r) approaches a limiting value of 1, which corresponds to the macroscopic density of the material.

  3. State of matter - Wikipedia

    en.wikipedia.org/wiki/State_of_matter

    In a string-net liquid, atoms have apparently unstable arrangement, like a liquid, but are still consistent in overall pattern, like a solid. When in a normal solid state, the atoms of matter align themselves in a grid pattern, so that the spin of any electron is the opposite of the spin of all electrons touching it.

  4. List of states of matter - Wikipedia

    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 ...

    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.

    A WISP (weakly interacting slender particle) is any one of a number of low mass particles that might explain dark matter (such as the axion) A GIMP (gravitationally interacting massive particle) is a particle which provides an alternative explanation of dark matter, instead of the aforementioned WIMP

  7. Dispersion (chemistry) - Wikipedia

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

    Dispersion is a process by which (in the case of solid dispersing in a liquid) agglomerated particles are separated from each other, and a new interface between the inner surface of the liquid dispersion medium and the surface of the dispersed particles is generated. This process is facilitated by molecular diffusion and convection. [4]

  8. Particle size - Wikipedia

    en.wikipedia.org/wiki/Particle_size

    Particle size is a notion introduced for comparing dimensions of solid particles , liquid particles , or gaseous particles . The notion of particle size applies to particles in colloids , in ecology , in granular material (whether airborne or not), and to particles that form a granular material (see also grain size ).

  9. Particle-size distribution - Wikipedia

    en.wikipedia.org/wiki/Particle-size_distribution

    The particle count is obtained by counting pulses. This pulse is proportional to the volume of the sensed particle. Advantages: very small sample aliquots can be examined. Disadvantages: sample must be dispersed in a liquid medium... some particles may (partially or fully) dissolve in the medium altering the size distribution. The results are ...
