Mo8-L2: Vocabulary Review

         Direction:  Each of the sentences below is false. Make the sentence true by replacing the underlined
                    word(s) with a term from the list below. Write your changes on the lines provided.

        conduction            convection           equilibrium           heat
        radiation             sublime              temperature           thermal conductor
        thermal insulator     vaporization



                              1. When the temperatures of materials that are in contact are the same, the materials
                                   are said to be in thermal convection.

                              2. To change from a solid state to a gas state without passing through the liquid state
                                   is to radiate.

                              3. The change of state from a liquid to a gas is called conduction.

                              4. The material that makes up a pot’s handle is a(n) thermal conductor.

                              5. Thermal energy can be transferred by conduction, convection, and vaporization.

                              6. The metal that makes up a pot is a(n) equilibrium.

                              7. Convection is the transfer of thermal energy by collisions between particles in
                                   matter.

                              8. The movement of thermal energy from a warm bottle of water to the cool air in a
                                   refrigerator is called temperature.

                              9. The transfer of thermal energy by the movement of particles from one part of a
                                   material to another is conduction.

                              10. The measure of the average kinetic energy of the particles in a material is
                                     sublimation.




          Mo8-L2: Key Concept Organizer

         Direction: On each line, write the term from the word bank that correctly completes each sentence. Some
                    terms may be used more than once or not at all.

        Celsius (°C)          container                    dense                Fahrenheit (°F)

        kinetic energy        motion                       particles            solids
        temperatures          thermal contraction          thermal energy       thermal expansion
        volume                water

         1. How thermal energy transfers in materials depends on the movement of
              in the materials.


         2. The SI unit for temperature is kelvin (K), but many scientists also use                                                                  to
              measure temperature.


         3. Heat is the movement of                               from a region of higher temperature to a
             region of lower temperature.

         4. The increase in volume that a material undergoes when its temperature increases is called
                                     .
