| heat | thermal energy moving from a warmer object to a cooler object |
| conduction | the transfer of heat from one end of a solid to the other, without the movement of matter itself |
| convection | the transfer of heat by the movement of currents within a fluid |
| specific heat | the amount of heat required to raise the temperature of 1 kilogram of a substance by one kelvin |
| radiation | the transfer of energy by electromagnetic waves |
| conductor | a material that conducts heat well (metals such as silver and stainless steel) |
| insulator | a material that does not conduct heat well (wood, wool, air) |
| convection current | a current caused by the rising of heated fluid and sinking of cooled fluid |
