  1. Warm-UpApril 12, 2013 • Write down the date and objective. • Objective: SWBAT review Unit 5 by competing in Amazing Race. • Complete the following warm-up questions: • 1. Label each graph as either pressure vs. temp, pressure vs. volume, or pressure vs. # of particles:

  2. Objective & Agenda • Objective: SWBAT review Unit 5 by competing in Amazing Race. Agenda • Lake Nyos • Gut check • Amazing Race • Review • Exit Slip • College FRIDAY!!

  3. Ideal Gas Law Lab Calculations

  4. Practice Problems- Part 2

  5. Lake Nyos Disaster • Read the article and answer questions 1-4 on a separate sheet of paper. • Write in complete sentences

  6. Analysis • Charlotte is located between two lakes, Lake Norman and Lake Wylie. Should people in North Carolina be concerned about a disaster like this happening? Write one paragraph that defends whether or not we should be concerned about this. Give evidence based on the information in the article.

  7. Tuesday’s test • Will cover: • Conceptual Pressure Problems • Pressure Conversions • Partial Pressure • Ideal Gas Law • Combined Gas Law • P/V • V/T • All three variables

  8. Gut Check • My basketball is too pumped up. Name 3 ways I can lower the pressure (one each for V, n, and T). • Increase Volume, Decrease n, Decrease T • If I have 2 moles of gas held at a pressure of 4 atm and a temperature of 100 K, what is the volume of the gas? • 4.01 L • A gas takes up a volume of 5 liters, has a pressure of 2 atm, and a temperature of 100 K. If I raise the temperature to 200 K and lower the pressure to 1 atm, what is the new volume of the gas? • 20L • Convert 147 psi to mmHg. • 7,600 mmHg

  9. Amazing Race • Answer the question and show all work on your answer sheet (note the numbering) • One partner runs up and checks answer with me. If correctgrab the next question. If incorrectfix it. • First 3 groups to finish get Extra Credit on the exam Tuesday. • Once you finish you need to work on the Unit 5 Review which is due Monday

  10. Exit SlipApril 12, 2013 • A container holds the gases O2, CO2, and N2. If the total gas pressure of this container is 67 atm, and both O2 and N2 have a pressure of 12 atm, what is the pressure of CO2? • After casting a spell on a chemistry experiment, Harry Potter has a container with a pressure of 3040 torr, volume of 57 L, and temperature of 86oC. If the container started with a volume of 49 L and pressure of 5.5 atm, what was the initial temperature?

  11. COLLEGE FRIDAY!!
