3. That as the pressure on a gas increases the volume will decrease.

4. Indirect relationship; as one variable goes up the other goes down.

5. Kinetic Theory states that the particles in a gas are very far apart. Therefore when you compress a gas the particles move closer but do not have contact.

6. What does Charles’ Law state? That as you increase the temperature on a gas the volume will increase also.

7. Direct Relationship, as one variable goes up so does the other.

8. Kinetic Theory states that as the temperature increases the atoms which are in constant motion will move faster and expand. This causes an increase in volume.

9. It is the combination of Boyle’s and Charles’ Law because it is rare in the real world that only one variable will change at a time.

10. P1V1/T1 = P2V2/T2 or PV/T = k

11. Your answer should include a discussion of a temperature change and/or a pressure change and how the volume would change because of that.

12. Solid: very slow moving, close together particles Liquid: faster moving, they move in two dimensions Gas: very fast moving and very far apart, they move in three dimensions

13. Yes, anytime it is going through a phase change we have two states existing at the same time.

14. Melting: solid-liquid Boiling: liquid-gas Evaporation: liquid- gas below boiling Condensation: gas- liquid Freezing: liquid- solid Sublimation: solid-gas

15. That matter(mass) is neither created nor destroyed it simply changes form. This means that we cannot lose any mass in a chemical reaction.

16. If mass cannot be created or destroyed then the number of atoms on one side of the chemical reaction should match the number on the other side.

17. No, as long as there is the same number of elements of each type.

18. At the S-L line the substance is melting and freezing at various pressures.

19. About 200 mmHg

20. It is the point at which all 3 states of matter can exist at the same time.

21. All gases consist of molecules and that those molecules are in motion. They are very far apart compared to solids and liquids and when they collide with each other it is perfectly elastic. The attractive forces between the gas molecules is very weak and that the temperature of a gas is directly proportional to the average kinetic energy of the gas

22. The higher the temperature the faster the particles move and the more they collide with the thermometer. As they collide faster they apply pressure to the outside of the thermometer causing the liquid inside to rise higher.

23. The boiling points for each set of molecules.

24. 1; 2; 1; 2

25. 3; 1; 1; 1

26. 1; 6; 6; 6

27. 1atm x 4.6L = 2.2L x ? ? = 2.1 atm

28. 11.3L/ 398 = 5.3L / T 189 K

29. 12.3 ml( 1atm)/ 273 = V(4 atm)/373 4.20 ml

30. Indirect relationship; Boyle’s Law

31. Direct relationship; Charles’ Law

32. It is increasing

33. 55 g / 44 g/mole = 1.25 moles of CO2

34. 3 moles x 22.4 L/mole = 67.2 L

35. 1.204 x 10 24/ 6.02 x 10 23 = 2 moles 2 moles x 22.4 L /mole = 44.8 L

36. K = C +273

37. Because the Kelvin scale is based on absolute zero you can never have a negative value.

38. 278 C
