State of matter (solid, liquid, gas)

• States of matter

  • Solid
  • Liquid
  • Gas
  • Plasma
• Solid


  • Definite shape and volume, particles closely packed and vibrate in place
• Liquid


  • Definite volume but take the shape of their container, particles more loosely packed and able to move past each other
• Gas


  • Neither definite shape nor volume, particles far apart and move freely
• Changes in temperature and pressure


  Can cause matter to change states, such as melting from a solid to a liquid or evaporating from a liquid to a gas
• Examples of solids, liquids, gases, plasma


  • ABC
  • He 4.0026
  • MILK
  • Plasma
• Sublimation


  The process in which a substance changes directly from a solid to a gas without passing through the liquid state
• Sublimation process


  1. Sublimate (solid to gas)

  2. Melt (solid to liquid)

  3. Evaporate (liquid to gas)

  4. Desublimate (gas to solid)
• Plasma


  A fourth state of matter that exists at very high temperatures, where atoms are stripped of their electrons and become highly charged particles
• Kinetic theory of matter


  Explains how particles move and interact in each state of matter
• Intermolecular forces


  Influence the state of matter, such as hydrogen bonding, dipole-dipole interactions, and London dispersion forces
• Phase diagrams


  Show the relationship between temperature, pressure, and the state of a substance
• Changes in state


  Involve the absorption or release of energy (e.g. melting and vaporization require energy input, while freezing and condensation release energy)
• Matter can undergo phase transitions in both directions, such as condensation (gas to liquid) and evaporation (liquid to gas)</b>
• Impurities or additives


  Can alter the properties of a substance and its transition between states
