| Term | Definition |
|---|---|
| Temperature | measure of the average kinetic energy of the individual particles in matter |
| Fahrenheit Scale | most common temperature scale in the US; Freezing point: 32°F, Boiling point: 212°F |
| Celsius Scale | the most common temperature scale in the world; Freezing point: 0°C, Boiling point: 100°C |
| Heat | thermal energy moving from a warmer object to a cooler object |
| Heat engine | a device that creates the transformation of thermal energy to mechanical energy |
| Conduction | heat is transferred from one particle of matter to another without the movement of the matter Example: hot coils on a stove transferring heat to a pot of water |
| Convection | heat is transferred by the movement of currents within a fluid Example: the water moving in a boiling pot of water |
| Radiation | the transfer of energy by electromagnetic waves Example: the feel of the heat from a fire |
| Conductor | a material that conducts heat well Examples: Metal spoon, tile floor |
| Insulator | a material that does not conduct heat well Examples: Wood, wool, straw, paper |
| States of Matter | solid, liquid, and gas |
| Change of State | the physical change from one state of matter to another |
| Melting | the change of state from a solid to a liquid |
| Freezing | the change of state from a liquid to a solid |
| Evaporation | the change of state from a liquid to a gas |
| Condensation | the change of state from a gas to a liquid |
| Sublimation | the change of state from a solid to a gas |
| Deposition | the change of state from a gas to a solid |
| Kinetic Energy | energy in motion Example: Walking, throwing a ball |
| Potential Energy | energy not in motion Example: a rock, top of a roller coaster |
