Kinetic Molecular Theory

• explains the states of matter

  kinetic molecular theory
• a _ is composed of tiny particles that are always in motion


  matter
• helps explain observable properties and behaviors of solids liquids and gas

  kinetic molecular theory
• particles are constantly moving, _,_

  changing their direction and velocity
• measure of the degree of motion of the particles 


  temperature
• when the temperature goes up, velocity _

  increases
• solids - sublimation (gas), gas - condensation(liquid), liquid - freezing (solid)

  gas - deposition(solid), solid - melting (liquid), liquid - evaporation(gas)
• properties of matter


  volume, density, compressibility, motion of molecules
• states of matter

  solid liquid gas
• gas density


  low
• compressibility of gas- easy to compress, liquid- cannot be, solids- cannot be
• motion of molecules: random fast cover large distances


  gas
• motion of molecules: random medium speed limited distances


  liquid
• motion of molecules: compressed vibration in place


  solids
