  1. Properties of Matter Phase Changes Energy & Thermo- Dynamics Temp. and heat Pressure 100 100 100 100 400 100 200 200 200 200 200 300 300 300 300 300 400 400 400 400 400 500 500 500 500 500

  2. These are the two main categories of matter. 1, 100

  3. What are pure substances and mixtures? 1, 100

  4. These are four of the 7 physical properties of matter we learned. 1, 200

  5. What are conductivity, malleability, density, hardness, viscosity, melting point, and boiling point? 1, 200

  6. Mixtures can be classified as solutions, colloids, or suspensions based on the size of these. 1, 300

  7. What are the largest particles? 1, 300

  8. These are the four main indicators that a chemical change has occurred. 1, 400

  9. What are formation of a precipitate, production of a gas, change of color, and releasing or taking in heat? 1, 400

  10. This is the type of mixture that cannot be filtered but does disperse light. 1, 500

  11. What is a colloid? 1, 500

  12. This is the phase change where a liquid turns into a gas. 2, 100

  13. What is vaporization? 2, 100

  14. This category of phase change occurs when the substance absorbs heat from its surroundings. 2, 200

  15. What is endothermic? 2, 200

  16. During a phase change the temperature does this. 2, 300

  17. What is stays the same. 2, 300

  18. This is the approximate condensation temp. of the substance whose T vs. E graph is below. 2, 400

  19. What is -33 oC? (same as boiling point) 2, 400

  20. These are the states of matter at -120 C, -80C, -40C, and 0C for the substance shown in the T vs. E graph below. 2, 500

  21. What are solid (-120C) , solid (-80C), liquid (-40C), gas (0C)? 2, 500

  22. Any type of energy can be categorized as one of these two main types. 3, 100

  23. What are potential and kinetic energy? 3, 100

  24. Whenever energy transforms from one form to another, some of the energy is always lost as this. 3, 200

  25. What is heat? 3, 200

  26. The first law of thermodynamics says this. 3, 300

  27. What is energy can neither be created nor destroyed? 3, 300

  28. When heat flows, it always flows in this direction. 3, 400

  29. What is from hot to cold? (everything flows from high concentration to low concentration by itself, you can think of cold as a low concentration of heat) 3, 400

  30. These are two of the three things that are often used to show the kinetic theory of matter is correct. 3, 500

  31. What are Brownian motion, thermal expansion, and diffusion? 3, 500

  32. This is what temperature is related to. 4, 100

  33. What is the average kinetic energy of particles 4, 100

  34. Of 0oC water and 0oC ice, this is the one with the greater total internal energy 4, 200

  35. What is 0oC water. 4, 200

  36. Of 0oC water and 0oC ice, this is the one with a greater average kinetic energy. 4, 300

  37. What is 0oC water and 0oC ice have the same average kinetic energy 4, 300

  38. This is why nothing can be cooled below absolute zero. 4, 400

  39. What is absolute zero is the temperature all molecular motion stops, since temperature measures average kinetic energy, if there is no motion, there is no KE, and thus no temperature, and you can’t make the molecules move slower than stopped. 4, 400

  40. This is why heat of vaporization is typically greater than heat of fusion for a particular substance 4, 500

  41. What is to vaporize, the molecules need to gain enough energy to completely break free of and separate from neighboring molecules, while when melting, the molecules need to only gain enough energy to be able to flow passed, but still touch the neighboring molecules. 4, 500

  42. Pressure is defined as this. 5, 100

  43. What is force distributed over a certain area? 5, 100

  44. Gas pressure in a closed container is caused by these. 5, 200

  45. What are collisions between the gas particles and each other and the sides of the container?Pressure is affected by other things, but not caused by them 5, 200

  46. These four things affect gas pressure in a closed container. 5, 300

  47. What are number of particles, temperature of the gas, volume of the container, and type of gas? 5, 300

  48. These are the two pairs of quantities that are directly proportional in closed container of gas when everything else is constant. 5, 400

  49. What are temperature and volume (Charles’ Law) and temperature and pressure (Gay-Lussac’s Law)? 5, 400

  50. This is the final size of an air bubble if it starts out 10ml, with a temperature of 10oC and pressure of 4atm, and then proceeds to go to a location with a pressure of 2atm and temperature of 20oC. 5, 500
