1. LIAR LIAR

2. QUESTION ONE What temperature and pressure is STP?

3. According to our notes, STP is O degrees Celsius and 1 atm.

4. QUESTION TWO What is standard pressure in mmHg?

5. 760 mmHg = 1 atm

6. QUESTION THREE What is room temperature…in Kelvin?

7. 298 K = 25 degrees C

8. QUESTION FOUR If you decrease the pressure on a gas, what happens to its volume?

9. It increases!

10. QUESTION FIVE How are temperature and pressure related (directly or inversely)?

11. Directly!

12. QUESTION SIX What makes a gas ideal?

13. It follows all of the rules of the kinetic molecular theory!

14. QUESTION SEVEN What does the kinetic molecular theory say about the molecules of a gas?

15. That the molecules are infinitely small and there are virtually no intermolecular forces holding the molecules together.

16. QUESTION EIGHT What are the four possible units of pressure (full names please!)?

17. Atmospheres • Millimeters of mercury • Torr • Kilopascals

18. QUESTION NINE What is partial pressure?

19. Partial pressure is the pressure that each of the components in a mixture of gases would exert if the other gases in the mixture were removed.

20. QUESTION TEN When at STP, what do you need to use to convert between moles and liters?

21. 1 mole = 22.4 L

22. QUESTION ELEVEN When not at STP, how do you convert between moles and liters?

23. You use PV = nRT!

24. QUESTION TWELVE What is the name of the law that describes that pressure is directly proportional to temperature?

25. Gay-Lussac

26. QUESTION THIRTEEN What is the law that describes that pressure is inversely proportional to volume?

27. Boyle’s

28. QUESTION FOURTEEN What is the law that describes that the total pressure of the gas mixture is equal to the partial pressures of the gases that make up the mixture?

29. Dalton’s Law of Partial Pressures

30. QUESTION FIFTEEN Which ideal gas constant # would you use in PV = nRT if pressure was measured in atmospheres?

31. 0.08206
