#state_of_matter__state  (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); "the solid state of water is called ice"
  supertype:  #chemical_phenomenon  a natural phenomenon involving chemistry (as changes to atoms or molecules)
  subtype:  #phase.state_of_matter__form  (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: "the reaction occurs in the liquid phase of the system"
     subtype:  #dispersed_phase__dispersedphase__dispersed_particles__dispersedparticle  (of colloids) a substance in the colloidal state
     subtype:  #dispersing_phase__dispersion_medium__dispersing_medium  (of colloids) a substance in which another is colloidally dispersed
  subtype:  #liquidness__liquid__liquidity  the state in which a substance exhibits a characteristic readiness to flow with little or no tendency to disperse and relatively high incompressibility
  subtype:  #solidness__solidnes  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 an definite size and shape
  subtype:  #gas.state_of_matter__ga  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
  subtype:  #plasma  (physical chemistry) the gaseous state of hot ionized material consisting of ions and electrons and present in the stars and fusion reactors: sometimes regarded as a fourth state of matter distinct from normal gasses
