Term | Definition |
amorphous solid | solid made up of particles that are not arranged in a regular pattern. |
boiling | When vaporization takes place throughout a liquid. |
boiling point | Each liquid boils only at a certain temperature |
Boyle's Law | The relationship between the pressure and volume of a gas |
Charles' Law | Charles found that when the temperature of a gas is increased at constant pressure, its volume increases. When the temperature of a gas is decreased at constant pressure, its volume decreases. |
condensation | The opposite of vaporization |
crystalline solid | solid that is made up of crystals in which particles are arranged in a regular, repeating pattern |
evaporation | When vaporization takes place only on a liquid’s surface |
fluid | Any substance that can flow |
freezing | the change of state from liquid to solid—the reverse of melting |
gas | A state of matter with no definite shape or volume. |
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 |
melting point | In most pure substances, melting occurs at a specific temperature |
pressure | the force of its outward push divided by the area of the walls of the container |
solid | A state of matter that has a definite shape and a definite volume |
sublimation | when the surface particles of a solid gain enough energy to become a gas |
surface tension | The result of an inward pull among the molecules of a liquid that brings the molecules of a liquid that brings the molecules on the surface closer together; causes the surface to act as if it has thin skin. |
vaporization | The change from a liquid to a gas |
