| amorphous solid | a solid made up of particles that are not arranged in a regular pattern |
| boiling | the process that occurs when vaporization takes place inside a liquid as well as the surface |
| Boyle's law | the relationship between the pressure and volume of a gas; when volume increases, pressure decreases |
| Charles's law | the relationship between the temperature and volume of a gas; when temperature increases, volume increases |
| chemical energy | a form of energy that comes from chemical bonds |
| chemical reaction | a process in which substances undergo chemical changes, forming new substances with new properties |
| condensation | the change of state from a gas to a liquid |
| crystalline solid | a substance that is made up of crystals in which particles are arranged in a regular, repeating pattern |
| directly proportional | a term used to describe the relationship between two variables whose graph is a straight line pasing through the point (0,0) |
| evaporation | the process that occurs when vaporization takes place only on the surface of a liquid |
| fluid | any substances that can flow |
| freezing | the change in state from a liquid to a solid |
| gas | a state of matter with no definited shape or volume |
| graph | a diagram that shows how two variables are related |
| law of conservation of energy | the principle that the total amount of energy remains the same during physical or chemical change |
| liquid | a state of matter that has no definite shape but has a definite volume |
| melting | the change in state from a solid to a liquid |
| pressure | the force pushing on a surface divided by the area of that surface |
| solid | a state of matter that has a definite volume and a definite shape |
| sublimation | the change in state from a solid directly to a gas without passing trhough the liquid state |
| temperature | a measure of the average energy of motion of the particles of a substance |
| thermal energy | the total energy of a substance's particles due to their movement or vibration |
| vaporization | the change in state from liquid to a gas |
| vary inversely | the term used to describe the relationship between two variables whose graph forms a curve that slopes downward |
| viscosity | the resistance of a liquid to flowing |
