Presentation Transcript

  1. Day 10 • Calculating Energy for Phase Change!

  2. Calculating energy (e) needed to change phase • Where on the graph is a change in phase? • Is there a temperature change?

  3. Heating Curve for H2O

  4. Much more energy must be transferred as heat to vaporize water than to melt ice. • Heat of Fusion • Heat needed to melt ice into water • Heat of Vaporization • Heat needed to vaporize liquid water into gas

  5. Heating Curve for H2O

  6. E = Hf x m • E = Hv x m • E = energy (Joules) • Hf = Heat of fusion for water (333 J/g) • Hv = Heat of vaporization (2260 J/g) • m = mass (grams)
