  1. Thermochem HW 1

  2. Separate by exothermic and Endothermic • Melting • Freezing • Vaporization • Condensation • Sublimation • Deposition

  3. Explain • Explain why you grouped the phase changes the way you did. • Base your explanations around molecular motion.

  4. Draw and explain • Draw 2 graphs with heat on the y-axis and time on the x-axis. • Draw 1 for an exothermic process and 1 for an endothermic process. • Explain the reason for why you drew each graph the way you did. • 1 Paragraph each

  5. Not exo- or endo- thermic • Evaporation – explain how this process does not release or absorb energy?
