  1. What Happens when Water Boils? [Lecture for Day 5, after Boiling Point lab and data analysis]

  2. What did we see when water is heated? Water + Heat = Boiling Water = Steam

  3. Adding Energy to a System(Kinetic Theory) Molecular motion -linear movement -vibration -molecular rotation Is this a drawing of a solid, liquid, or gas?

  4. Molecular Motion in Liquid Water Hot vs. Room Temperature vs. Cold Water—Can we see the difference in motion? wow.osu.edu/.../statesofmatter/psm1/movmol.html

  5. Adding Energy to a System Adding energy increases motion and decreases order fig.cox.miami.edu/.../150/chemistry/sf2x10b.jpg

  6. So What Happens When Water Boils?(in Kinetic Terms)

  7. Phase Change Curve for Water Idealized heating curve for the conversion of ice to water to steam (Briwn, LeMay, and Burnsten10th Edition pg. 456
