| Temperature | Average NRG of particles in a substance. |
| Thermal Energy | The totla NRG of the particles in a substance. |
| HEAT | NRg transfered from a hotter sub. to a cooler one. |
| Conduction | Transfer of NRg through a material by direct contact. |
| Thermal Conductivity | The measure of the ability for the material to conduct heat. |
| Convection | The process of transfering heat by the circular motion of particles. |
| Radiaton | The transfer of NRG in a wave like form. |
| Radiant Energy | NRG transformed by means of radiation. |
| Heat Waves/ Rays | Infared radiation. |
| Infared Radiation | A type of radiant NRG. |
| Reflection | Occurs if the NRg cant get past the particles at the surface. |
| Absorbtion | Occurs if the NRG penetrates part way into the object. |
| Transmittance | When the radiant NRG passes through an object without being absrbed by the particles. |
| Emittance | To radiate absorbed NRG (to giveoff). |
| Heat Insulator | A material used to reduce the amount of heat transfer. |
| RSI Value | Resistance to heat transfer of a material of a specific thickness. |
| Greenhouse Effect | a warming of the air caused by the trappingof heat. |
| Specific Heat Capacity | The amount of NRG required to cause a 1Deg change in 1kg of a substance. |
| Law Of Conservation Of energy | NRG is never created nor destroyed by ordinary means. |
| Principle Of Heat Transfer | In a perfectly insulated system when 2 substances are mixed, the heat released by the hotter substance is equal to the NRG gained by the cooler one. |
| Hydroelectricity | Electricity produced by thr force of running water as an NRG source. |
| Solar NRG | Radiant NRG that reaches Earth from the Sun. |
