| energy | the ability to do work or cause change |
| state | the form in which matter exists |
| solid | a state of matter that has a definite shape and a definite volume |
| liquid | a state of matter that has no definite shape, but a definite volume |
| gas | a state of matter with no definite shape or volume |
| freezing point | the temperature at which a liquid freezes |
| boil | to heat a liquid to the point at which it changes to a gas |
| boiling point | the temperature at which a liquid boils |
| potential energy | the an object has because of its position; also the internal stored energy of an object, such as energy stored in chemical bonds |
| kinetic energy | energy that an object has due to its motion |
| energy transformation | a change from one form of energy to another |
| law of conservation of energy | the rule that energy cannot be created or destroyed |
| friction | the force that two surfaces exert on each other when they rub against each other |
| temperature | how hot of cold something is |
| fahrenheit scale | the temperature scale on which water freezes at 32 degrees and boils at 212 degrees |
| celsius scale | the temperature scale on which water freezes at 0 degrees and boils at 100 degrees |
| kelvin scale | the temperature scale on which zero is the temperature at which no more energy can be removed from matter |

| heat | the transfer of thermal energy from a warmer object to a cooler object |
| convection | the transfer of thermal energy by the movement of a fluid |
| convection current | the movement of a fluid, cause by differences in temperatures, that transfers heat from one part of the fluid to another |
| radiation | the transfer of energy by electromagnetic waves |
| conduction | the transfer of thermal energy from one particle of matter to another |
