| conduction | heat is transfered through direct contact |
| convection | heat is transfered through a liquid or gas through currents |
| radiation | heat is transfered through a vacuum or matter by electromagnetic waves |
| thermal conduction | the handle of a metal spoon gets hot when left in hot soup |
| convection current | the vertical movement of air currents due to temperature variations |
| conductors | substances that allow energy to flow through them easily |
| insulators | substances that resist the flow of energy through them |
| specific heat | the energy required to raise the temperature of 1 g of a substance 1 K |
| metals | good conductors |
| glass, plastic, wood | good insulators |
