  • 5. Topic:Power Notes- Phases ofMatterMatterWhat are some differencesyou already know about thesephases?What are some similaritiesyou already know about thesephases?
  • 6. Most of the elements -SOLID – at standardon the Periodic Table of temperature and pressure.Elements exist in whatstate? LIQUIDS – However, ¾ of ourVery few of the planet is covered with theelements exist on the liquid known as water.Periodic Table as? GASES – they have no definiteWhat state of matter shape or volume. They expandmakes up only about 11 to fill the container theyelements on the occupy.Periodic Table?
  • 7. Although at standard -The most abundant form oftemperature and matter in the Universe.pressure there are noPLASMA phases on thePeriodic Table, thisphase of matter existsat extremely highheats. Movement of the particlesPhases of matterdepends on?What is this movement Amount of energy in adependent upon? substance.
  • 8. Matter with lots of -higher temperatureskinetic energy usually -particles that are movinghave what? wildly -particles that are far apartWhich phase has the Plasmasmost kinetic energy?Which phase has the Solids (BEC)least kinetic energy?
  • 9. Energy Scale High Low Energy Phase Energy Plasma Gas Liquid Solid BEC* * Rubidiu m at 0 KelvinIllustrate, Color and Label an example of each Phase*Plasma and BEC’s can be similar…everything elseshould be unique * Bose Einstein Condensates
  • 10. What words describe -MELTING– when a solidPhase Change? moves to the liquid state when heat is added. FREEZING – when a liquid moves to the solid state. This happens when heat is released. EVAPORATION – when a liquid moves to the gaseous state. Heat needs to be added for this to happen.
  • 11. What words describe -CONDENSATION– when aPhase Change? gas moves to the liquid state when heat is released. SUBLIMATION– when a solid moves to the gas state skipping the liquid state. This happens when heat is added. DEPOSITION– when a gas moves to the solid state skipping the liquid state. Heat needs to be released for this to happen.
  • 12. Remember: According to the kinetic theory of matter, all matter is made up of moving particles. The states of matter are dependent upon how fast the particles are moving and how much attraction the molecules have for one another.
  • 13. In order for matter to changefrom one state to another,energy must be added orremoved.Each type of substance has itsown freezing, melting andboiling points. In other words,different substances changestates at differenttemperatures.
  • 14. Phase ChangesDifferent Substances have their own unique melting & boiling points.Color each thermometer according to the key to indicate at which and/or between which temperatures it is a solid, liquid or gas.
  • 15. Questions & Review & Check1) Answer each question using your power notes for Phase Change.2) Do a Review and Reflect on all your notes. +, ,-
