  2. What is Kinetic Energy?

  3. The energy of motion

  4. What is matter?

  5. Anything with mass and volume

  6. What makes particles move?

  7. Energy

  8. How do particles of gas move?

  9. They move around quickly and are very far apart

  10. Name the seven parts of the Kinetic Molecular Theory

  11. All matter is made up of very small particles There is empty space between particles Particles are constantly moving Solid particles are packed together and can only vibrate Liquid particles can only move by sliding past each other Gas particles move very quickly and very far apart Energy makes particles move

  12. How is PMM different from KMT?

  13. KMT is expanded and explains movement in more detail

  14. Why can some materials move past others?

  15. Because some particles are farther apart

  16. Give an example of a solid, liquid, and a gas

  17. Answers will vary

  18. Explain in detail what the PMM is.

  19. PMM is the theory that explains the movement and behavior of particles in solids, liquids, and gases.

  20. Name the 4 parts of the PMM

  21. 1. All matter is made up of very small particles 2.There are spaces between particles 3. The particles that make up particles are always moving 4. The particles are attracted to one another

  22. What happens when you add energy to a material?

  23. You increase the kinetic energy

  24. What is Thermal Expansion?

  25. What happens to the molecules in Thermal Contraction?

  26. The process of a substance increasing in volume when it’s temperature is increased

  27. The particles slow down, which means they take up less space

  28. How does a thermometer show different temperatures?

  29. The liquid inside the thermometer expands and contracts , causing it to get higher or lower

  30. Why are electrical wires hung loosely?

  31. In different temperatures, the particles inside the wires contract and expand. If they were strung tightly, they would break

  32. What is Heat?

  33. Heat is the energy transferred from one material or object as a result of different temperatures

  34. What is Thermal Energy?

  35. Thermal Energy is the total energy of the particles making up a substance

  36. What would happen if two objects with different thermal energies were to come in contact?

  37. The thermal energy from the warmer of the two would move to the colder one

  38. What is the difference between heat and temperature?

  39. Heat is the energy transferred from one material or object as a result of different temperatures, while temperature is a measure of the average kinetic energy of the particles in a substance

  40. What happens when you touch a hot cup of Tea?

  41. The heat from the cup transfers into your hand, because your hand has a lower thermal energy

  42. What is Sublimation?

  43. Sublimation is the change of state from a solid to a gas, skipping the liquid stage

  44. What is called when a gas changes into a liquid?

  45. Condensation

  46. What is Deposition?

  47. The change of state from a gas to a solid

  48. What is the melting point?

  49. The melting point is the temperature at which a solid turns to liquid

  50. What are the six terms for the changes of state
