States Of Matter

    Matters generally exists in the four forms of solid, liquid, gas and plasma.

  • Solids are tightly packed, usually in a regular pattern.
  • Solids has a stable, definite shape and volume.
  • Solids can only change their shape by force, as when broken or cut.
  • Example: Bar of steel and dry ice ( solid carbondioxide )
  • Liquids are close together with no regular arrangement.
  • Liquids has a definite volume, but takes the shape of its container.
  • Example: Water and Oil.
  • Gas are well separated with no regular arrangement.
  • Compressible fluid.
  • Gas has no definite volume and shape.
  • Example: Hydrogen and Oxygen.
  • Plasma does not have definite shape or volume.
  • Plasma may be formed by heating and ionizing gas.
  • Examples: Lightning, Electric sparks, and Fluorescent lights.
  • At very high temperature of stars, atoms lose their electrons. The mixture of electrons and nuclei that results is the plasma state of matter.
