Across
  1. 1. 2 different gases at the same temperature, pressure & volume have the same number of particles (molecules/atoms)
  2. 11. equal but opposite
  3. 13. the rate of evaporation is equal to the rate of condensation; closed system
  4. 16. when boiling occurs
  5. 17. how hard and how often the particles of a substance hit the walls of its container; units: Pa, atm
  6. 18. P1V1/T1 = P2V2/T2 (can also be written as P1 V1 T2 = P2 V2 T1)
  7. 22. where boiling occurs
  8. 23. particles are tightly packed, regular geometric pattern, crystal lattice, vibrate slowly in place, definite shape, definite volume, strong IMF's
  9. 27. solid to gas without stopping in the liquid phase
  10. 28. or boiling liquid to gas
  11. 35. when particles collide with each other or walls of container
  12. 36. IMF's; an invisible force between molecules
  13. 39. when evaporation occurs
  14. 41. the name of the Group 17 Elements; the only group that has all 3 phases of matter at room temperature
  15. 42. KMT; how particles behave
  16. 43. where evaporation occurs
  17. 44. particles don't stick together when colliding
Down
  1. 2. measures average kinetic energy of the particles of a substance
  2. 3. an element naturally found as a pair; HONClBrIF
  3. 4. the amount of space the particles of an object take up; units: cm^3, L
  4. 5. line the way gas particles move
  5. 6. vapor pressure = atmospheric pressure
  6. 7. and high vapor pressure; conditions for sublimation
  7. 8. gas to liquid
  8. 9. if one value changes, another value changes by the same amount and in the same direction
  9. 10. particles have no volume & no attraction (low pressure/high temperature)
  10. 12. as the pressure decrease, the volume increases at constant temperature
  11. 14. STP (Table A); serves as a frame of reference
  12. 15. a way to remember the 7 naturally occurring diatomic elements (H2, O2, N2, Cl2, Br2, I2, F2)
  13. 19. liquid to solid
  14. 20. do this to temperature to avoid multiplying by 0 or dealing with negative numbers
  15. 21. particles move fast, are far apart, take shape of and fill containers' volume entirely, very weak IMF's
  16. 24. particles are loosely packed, medium speed, take shape of container, definite volume, medium strength IMF's
  17. 25. 0 degrees Celsius or 273 K
  18. 26. vapor pressure < atmospheric pressure
  19. 29. when atmospheric pressure is at standard pressure (101.3 kPa/1 atm); at sea level
  20. 30. the particles are so small, it's as if they don't exist
  21. 31. gas to solid without stopping in the liquid phase
  22. 32. what you get when you multiply by zero
  23. 33. solid to liquid
  24. 34. particles do have volume & do have attraction (high pressure/low temperature)
  25. 37. As the temperature increases, the volume increases at constant pressure
  26. 38. 1 atm or 101.3 kPa
  27. 40. vapor pressure of four liquids reference table
