| temperature | is a measure of the average kinetic energy of the individual particles | 
| absolute zero | The temperature at which all atoms stop moving | 
| thermal energy | is the total energy of all of the particles in a system. | 
| heat | is thermal energy moving from warmer objects to cooler objects. | 
| transfer | moving energy | 
| conduction | the process of heat being transferred from one particle of matter to another without the movement of matter itself. (i.e. by touch) | 
| convection | the movement that transfers heat by the movement of currents within a fluid. | 
| radiation | the transfer of energy by the electromagnetic waves | 
| conductor | a material that conducts energy well. | 
| insulator | a material that does not conduct energy well. | 
| solid | has a definite volume and a definite shape. | 
| liquid | definite volume and no definite shape | 
| gas | variable volume and shape | 
| plasma | atoms that lose electrons from high temperatures | 
| matter | anything with mass and volume |
