  1. Changes of State Mrs. Andris

  2. 5 Changes of State • Sublimation • Solid turns directly into a gas • Condensation • Gas changes to a liquid • Evaporation • Liquid changes to a gas ga.water.usgs.gov ed101.bu.edu scottslumber.com

  3. 5 Changes of State • Melting • Solid changes to a liquid • Freezing • Liquid changes to a solid teacherlemon.blogspot.com ksl.com

  4. The identity does not change. • The energy of a substance changes. • The particles move faster or slower. • Your body gives off energy. Sweat gains energy from the body and evaporates. • The water vapor in the air condenses and turns into a liquid when it comes into contact with the cool surface of the glass.

  5. What was your temperature of the water? • The water is not boiling at 100° C. • A decrease in pressure lowers the boiling point.

  7. Changes of State for Water A. Solid, ice, particles moving slowly, low energy B. Melting, energy being added, ice changing to water C. Liquid, particles have more energy and are sliding past one another D. Boiling, evaporation, liquid water changing to water vapor E. Water vapor, particles moving fast and breaking away from each other.

  8. 11. Mass cannot be created or destroyed. 12. During a change of state, mass is conserved. The total mass of the substances undergoing a change stays the same before and after the change. 13. Energy cannot be created or destroyed, it changes form. 14. When matter changes state, energy changes from one form to another.
