Thermal Energy
| term | definition |
|---|---|
| temperature | the average amount of kinetic energy in the particles of a substance |
| thermal energy | the total amount of energy in the particles of a substance |
| heat | thermal energy that is moving |
| conduction | thermal energy is transferred between two touching objects or substances |
| convection | movement of thermal energy through currents in a fluid such as a gas or liquid |
| radiation | movement of thermal energy in the form of waves |
| conductor | a substance that allows thermal energy to pass into or out of it easily |
| insulator | a substance that does not conduct heat well |
| specific heat | the amount of energy required to raise the temperature of one kilogram of a substance by one Kelvin |
| vaporization | liquid state of matter becomes a gas |
| evaporation | liquid state of matter becomes a gas at the surface of a liquid |
| sublimation | solid state of matter skips the liquid phase to become a gas |
| condensation | gas state of matter looses thermal energy to become a liquid |
| thermal expansion | as thermal energy increases, the particles of a substance spread out causing this to happen |
| bimetallic strips | two different metals are joined together, when heated one expands faster than the other causing the piece of metal to bend in a curve |
| combustion | the process of burning a fuel |
