| heat | flow of energy from one object / area to another |
| higher to lower | heat flows from |
| higher temperature area | heat source |
| lower temperature area | heat sink |
| conduction | heat transfer through contact |
| conductor | material that allows heat flow |
| insulator | material that blocks heat flow |
| metal | good conductor |
| cloth | good insulator |
| convection | bulk movement of molecules due to uneven heating |
| radiation | flow of heat without contact |
| example of conduction | you burn your hand on a stove burner |
| example of convection | water heated to boiling |
| example of radiation | feeling heat when you open an oven |
