Changes of state

  1. 1. CHANGES OF STATE
  2. 2. SOLID TO LIQUID • MELTING • HEAT (ADD ENERGY) - ENDOTHERMIC • INCREASES KINETIC ENERGY • INCREASES PARTICLE VIBRATIONS • DECREASE FORCES OF ATTRACTION B/W PARTICLES • DECREASE IN PARTICLE PATTERN – PARTICLES CAN SLIDE BY EACH OTHER
  3. 3. LIQUID TO SOLID • FREEZING • COOL (REMOVE ENERGY) - EXOTHERMIC • LOWERS KINETIC ENERGY • PARTICLES VIBRATE SLOWER • FORCES OF ATTRACTION INCREASE • INCREASE PATTERN OF PARTICLES – CAN’T SLIDE BY EACH OTHER
  4. 4. LIQUID TO GAS • EVAPORATION • HEAT LIQUID TILL IT BOILS (ADD ENERGY) - ENDOTHERMIC • KINETIC ENERGY INCREASES • VIBRATIONS INCREASE • NO FORCES OF ATTRACTION • NO PATTERN • PARTICLES MOVE FREELY
  5. 5. GAS TO LIQUID • CONDENSING • COOL TILL GAS CONDENSES (REMOVE HEAT) - EXOTHERMIC • KINETIC ENERGY DECREASES • VIBRATIONS DECREASE • FORCES OF ATTRACTION INCREASE • PATTERN INCREASES • PARTICLES ARE CLOSE TOGETHER BUT CAN SLIDE OVER EACH OTHER
  6. 6. SOLID TO GAS • SUBLIMATION – UNUSUAL STATE CHANGE DIRECTLY FROM SOLID TO GAS - ENDOTHERMIC • KINETIC ENERGY INCREASES • VIBRATIONS INCREASE • NO FORCES OF ATTRACTION • NO PATTERN • PARTICLES MOVE FREELY • EXAMPLES: “DRY ICE” SOLID CARBON DIOXIDE SUBLIMES TO GAS, IODINE
  7. 7. STATE CHANGE GRAPH A. ALL SOLID B. MELTING POINT – ALL ENERGY IS GOING INTO BREAKING FORCES OF ATTRACTION C.All Substance is Liquid and Temperature begins to Rise Again D.Boiling Point - All Energy is Going Into Breaking Forces of Attraction E. All Substance is a Gas and Temperature begins to Rise Again.
