    STATE OF MATTER

    Pronunciation (US): Play  (GB): Play

     I. (noun) 

    Sense 1

    Meaning:

    (chemistry) the three traditional states of matter are solids (fixed shape and volume) and liquids (fixed volume and shaped by the container) and gases (filling the container)play

    Example:

    the solid state of water is called ice

    Synonyms:

    state; state of matter

    Classified under:

    Nouns denoting stable states of affairs

    Hypernyms ("state of matter" is a kind of...):

    chemical phenomenon (any natural phenomenon involving chemistry (as changes to atoms or molecules))

    Attribute:

    solid (of definite shape and volume; firm; neither liquid nor gaseous)

    liquid (existing as or having characteristics of a liquid; especially tending to flow)

    gaseous (existing as or having characteristics of a gas)

    Domain category:

    chemical science; chemistry (the science of matter; the branch of the natural sciences dealing with the composition of substances and their properties and reactions)

    Hyponyms (each of the following is a kind of "state of matter"):

    form; phase ((physical chemistry) a distinct state of matter in a system; matter that is identical in chemical composition and physical state and separated from other material by the phase boundary)

    liquid; liquid state; liquidity; liquidness (the state in which a substance exhibits a characteristic readiness to flow with little or no tendency to disperse and relatively high incompressibility)

    solid; solid state; solidness (the state in which a substance has no tendency to flow under moderate stress; resists forces (such as compression) that tend to deform it; and retains a definite size and shape)

    gas; gaseous state (the state of matter distinguished from the solid and liquid states by: relatively low density and viscosity; relatively great expansion and contraction with changes in pressure and temperature; the ability to diffuse readily; and the spontaneous tendency to become distributed uniformly throughout any container)

    plasma ((physical chemistry) a fourth state of matter distinct from solid or liquid or gas and present in stars and fusion reactors; a gas becomes a plasma when it is heated until the atoms lose all their electrons, leaving a highly electrified collection of nuclei and free electrons)
