state of matter

Definitions of state of matter

n (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)

hide 8 types...
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
(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
interplanetary gas
a rarefied flow of gas and charged particles (plasma) that stream from the sun and form the solar wind
dispersed particles, dispersed phase
(of colloids) a substance in the colloidal state
dispersing medium, dispersing phase, dispersion medium
(of colloids) a substance in which another is colloidally dispersed
Type of:
chemical phenomenon
any natural phenomenon involving chemistry (as changes to atoms or molecules)
