CHEMISTRY 2001 NAME PROBLEM SET #11: Condensed States of Matter DATE PERIOD READ CH. 9 WHILE SOLVING THESE PROBLEMS! 1. Define each of the following terms: a. kinetic energy b. kinetic theory c. temperature (It’s glossary time!) 2. In your own words, write the three assumptions of the kinetic theory of gases: (1) (2) (3) 3. Explain why we call liquids and solids “condensed” states of matter: 4. Why does evaporation lower the temperature of a liquid? 5. Explain why increasing the temperature of a liquid increases its rate of evaporation. 6. Use Figure 9.12 to determine the boiling point of each of these liquids: a. ethanoic acid at 27 kPa b. chloroform at 80 kPa c. ethanol at 53 kPa
