Transcript

  • 1. Changes in State
  • 2. Changes in State
    • 3 Ways State of Matter Changes
    • -Evaporation
    • -Sublimation
    • -Condensation
  • 3. Evaporation
    • When liquid changes to a gas when the temperature is above the boiling point
    • 100 °C, 212°F or 373 K
  • 4. Evaporation Pictures
  • 5. Sublimation
    • When a solid changes directly to a gas without going through the liquid state.
  • 6. Sublimation Pictures
  • 7. Condensation
    • When a gas changes to a liquid when cooled to or below the boiling point.
  • 8. Condensation Pictures
  • 9. Heat/Energy
    • Joules- measurement of energy (like calories).
    • 4.184 calories= 1 Joule
    • 1000 Joules= 1 kJ (kiloJoule)
  • 10. Heat of Fusion
    • Amount of energy needed to change from a solid to a liquid. The heat of fusion for water is 334 kJ/kg.
  • 11. Heat of fusion
  • 12. Heat of Vaporization
    • Amount of energy needed to change from liquid to a gas. The heat of vaporization of water is 2260 kJ/kg.
  • 13. Which requires less energy?
    • Water going from a solid to a liquid.
    • OR
    • Water going from a liquid to a gas.
