Key ideas in Matter in Motion: Phase and Energy

  • Added energy is consumed by breaking intermolecular bonds during phase transitions
  • Lower atmospheric pressure allows molecules to escape into gas at lower temperatures
  • Temperature measures average kinetic energy, which remains constant during a plateau
  • Boiling occurs when vapor pressure equals the surrounding atmospheric pressure
  • Why temperature plateaus during a phase change
  • The effect of atmospheric pressure on boiling point
  • The triple point requires a specific, unique combination of temperature and pressure
  • Sublimation occurs when a solid's vapor pressure exceeds ambient pressure before it melts
  • At this point, small changes can shift the substance into any of the three states
  • Dry ice (solid CO2) sublimes at room pressure because its liquid phase requires high pressure
  • Conditions required for sublimation versus melting
  • The fastest, highest-energy molecules are the first to break free into the air
  • The unique conditions of the triple point
  • The loss of high-energy molecules reduces the average kinetic energy of the liquid left behind
  • The mechanism of evaporative cooling
  • Existing chemical bonds must be destabilized before atoms can rearrange
