  • What is temperature?
    The measure of the average kinetic energy of the particles of a substance
  • Give an example of a thermal conductor
    Metal, carbon, aluminum, etc.
  • If you jump into water on a hot summer day and the water is cold, that is because___-
    water has a high specific heat
  • Most materials do what when heated?
    expand
  • Kinetic energy is the energy of_____
    motion
  • Low specific heat is what?
    Requires less thermal energy to change temp
  • True or false, the average kinetic energy of the particles increases as the temperature
    True
  • Why does running hot water of a metal jar make it easier to open?
    It expands
  • What temp are the particles moving the fastest in a pencil?
    50
  • What is a thermal conductor?
    Allows energy to flow through easily
  • Substances with a lower specific heat will experience less of a temperature change. True or false?
    False
  • How is heat transferred between a hot and cold object by conduction?
    The particles of the hotter object transfer kinetic energy to the particles of the cooler object
  • What is thermal equilibrium?
    When two materials have the same temperature
  • Give an example of an insulator
    wood
  • Do most metals have a lower specific heat
    yes
  • What is a thermal insulator?
    Does not let energy flow through easily
  • When a substance is cooled, it expands.
    False
  • When a pot of water is put on a stove, the water at the surface gets hot, why?
    convection
  • High specific heat is what?
    requires more thermal energy to change the temp
  • Compare hot tea and an iceberg in terms of temp and thermal energy
    Tea is hotter, iceberg has more thermal energy
