  1. a measure of the average kinetic energy of all the particles in an object
    temperature
  2. total energy, including kinetic and potential energy, of the particles that make up a material, is transferred by conduction, convection, and radiation
    thermal energy
  3. thermal energy that flows from a warmer material to a cooler material and is measured in joules
    heat
  4. amount of energy needed to raise the temperature of 1kg of a material by 1k
    specific heat
  5. transfer of energy through matter by colliding particles, takes place because particles are in constant motion
    conduction
  6. transfer of energy by the motion of heated particles in a fluid
    convection
  7. transfer of energy in the form of electromagnetic waves
    radiation
  8. material that doesn't allow electrons to move through it easily
    insulator
  9. energy from the sun that is free, renewable, and can be used to heat homes and buildings
    solar energy
  10. solar heating system device that absorbs radiant energy from the sun
    solar collector
  11. device that converts thermal energy produced by combustion into mechanical energy
    heat engine
  12. a type of heat engine that burns fuel inside the engine
    internal combustion engine
  13. device, such as a refrigerator, that removes thermal energy from one place and transfers it to another place at a different temperature
    heat mover
  14. specific heat
    the amount of heat needed to raise the temperautre of 1kg of a substance by 1k
  15. thermal energy of an object
    the total kinetic and potential energy of the molecules in the object
  16. what is thermal energy transferred by?
    conduction, convection, and radiation
  17. when does conduction and convection occur?
    conduction and convection can only occur matter is present
