  1. bimetallic strip: a strip consisting of two metals that bends with a rise in temperature
  2. boiling point: Temperature at which a liquid boils
  3. compression stroke: the mixture is squeezed into a smaller space as the piston moves back up
  4. conduction: transfer of heat between particles within a substance
  5. convection: the transfer of heat by the movement of currents within a fluid
  6. exhaust stroke: crankshaft turns, and the piston is forced back up pushing exhaust gas out of the cylinder
  7. external combustion engine: an engine powered by fuel burned outside the engine
  8. freezing point: the temperature at which a liquid freezes
  9. ignition: spark plug ignites mixture converting chemical energy to thermal energy making mixture a gas
  10. insulator: a material that does not allow heat to move through it easily.
  11. intake stroke: a mixture of gasoline and air enters a cylinder as the piston moves down
  12. internal combustion engine: an engine that burns fuel inside cylinders within the engine
  13. melting point: the temperature at which a solid becomes a liquid
  14. power stroke: as the heated gas expands pushing down the piston thus the piston moves the crankshaft
  15. radiation: the transfer of energy by electromagnetic waves
  16. refrigerator: a device that uses outside energy source to transfer thermal energy from a cool area to a warm area
  17. specific heat: the heat required to raise the temperature of one gram of a substance one degree kelvin
  18. states: liquid, solid, and gas
  19. thermal expansion: the expansion of matter when heated
  20. thermostat: heat-regulating device
