different between liquid vs nematic

English

Etymology

From Middle English liquide, from Old French liquide, from Latin liquidus (“fluid, liquid, moist”), from lique? (“to be liquid, be fluid”). Doublet of liquidus. As a term for a consonant, it comes from Latin liquida (c?ns?n?ns), a calque of Ancient Greek ????? (????????) (hugròn (súmph?non), “liquid consonant”).

Pronunciation

• enPR: l?k'w?d, IPA^(key): /?l?kw?d/
• Hyphenation: liq?uid

Noun

liquid (countable and uncountable, plural liquids)

1. A substance that is flowing, and keeping no shape, such as water; a substance of which the molecules, while not tending to separate from one another like those of a gas, readily change their relative position, and which therefore retains no definite shape, except that determined by the containing receptacle; an inelastic fluid.

   Coordinate terms: solid, gas

   Hyponyms: ideal liquid, non-ideal liquid

2. (phonetics) A class of consonant sounds that includes l and r.

   Hypernyms: approximant, consonant

   Coordinate term: glide

Usage notes

The differentiation of a liquid as an incompressible fluid is not strictly correct, experiments having shown that liquids are compressible to a very limited extent. See fluid.

     It is easy to see, however, that the same coefficients in nematics determine the adiabatic deformations also.

   • 1988, Masao Doi, The Theory of Polymer Dynamics, page 368,

     For low-molecular-weight nematics, it has been known that the constitutive equation of nematics is entirely different from that for isotropic liquids.

   • 1996, Lev M. Blinov, Vladimir G. Chigrinov, Electrooptic Effects in Liquid Crystal Materials, page 274,

     Electrohydrodynamic instabilities in nematics could be classified according to the dependence of the threshold voltage (or field) on the physical parameters of the liquid crystal, cell geometry, field frequency, etc.
