Thermal Energy
| Term | Definition |
|---|---|
| temperature | a measure of the average kinetic energy of the particles in a substance |
| thermal expansion | the expansion of matter when it is heated |
| Fahrenheit scale | most common temperature scale in the US |
| Celsius scale | most common temperature scale outside the US; the preferred temperature scale of scientists |
| absolute zero | the temperature at which no more energy can be removed from matter |
| heat | thermal energy moving from a warmer object to a cooler object |
| specific heat | the amount of energy required to raise the temperature of 1 kg of a substance by 1 degree kelvin |
| conduction | the transfer of heat from one particle of matter to another particle |
| convection | the transfer of heat by the movement of currents through a fluid |
| convection current | a circular motion resulting from the rising of a heated fluid and the sinking of a cooled fluid |
| radiation | the transfer of energy by electromagnetic waves through space |
| conductor | a material that conducts heat easily |
| insulator | a material that does not conduct heat well |
| change of state | the physical change from one state of matter to another |
| melting | the change from the solid to the liquid state of matter |
| freezing | the change from the liquid to the solid state of matter |
| evaporation | the change when surface liquids change to a gas |
| boiling | the change when the entire mass of liquid changes to gas |
| condensation | the change from the gas to the liquid state of matter |
