| Question | Answer |
| Solid | A state of matter that has a definite shape and a definate volume. Vibrates in the container in a FIXED position. |
| Crystalline solid | A solid thatis made up of crystals in which particles are arranged in a regular repeating pattern. |
| Amorphous solid | A solid made up of particles that are not arranged in a regular pattern. Does not melt at a distinct temperature. |
| Liquid | A state of matter that has no definate shape but has a definate volume. Particles move freely around eachother. Takes shape of lower part of contiainer. |
| Fluid | A substance that can easily flow. Can be a gas or a liquid. |
| Surface tension | The result of an inward pull among the molecules of a liquid that brings the molecules on the surface closer together. Causes water to make a round drop. |
| Viscosity | A liquid's resistance to flowing. |
| Gas | A state of matter with no definate shape or volume. Little gravitatonal attraction, high energy, takes shape of entire container. |
| Melting | The change from the solid to the liquid state of matter. Endothermic physical change. |
| Melting Point | The temperature at which a substance changes from a liquid to a solid. Both a solid and a liquid are present on a horizontal line where thermal energy changes but temperature remains the same. |
| Freezing | The change from the liquid to the solid state of matter. Exothermic physical change. |
| Vaporization | The change of state from a liquid to a gas. Can be boiling or evaporation. |
| Evaporation | The process wich occurs when vaporization takes place only on the surface of a liquid. |
| Boiling | The process which occurs when vaporization takes place inside a liquid as well as on the surface. B for BELOW. |
| Boiling point | The temperature at which a substance changes from a liquid to a gas. Both a liquid and a gas state are present on a horizontal line. |
| Condensation | The change from the gaseous to the liquid state of matter. An exothermic physical change. |
| Sublimation (poof). | The change in state from a solid directly to a gas without passing through the liquid state. Dry Ice. |
| Pressure | The force exerted on a surface devided by the total area over which the force is exerted. High heel has high ___ and snow shoe has low ____. |
| Boyle's law | A principle that describes the relationship between the pressure and volume of a gas at constant temperature. CONCEPT NOT NAME IS TESTED. |
| Charles's law | A principal that describes the relationship between the temperature and volume of a gas at constant pressure. CONCEPT NOT NAME IS TESTED. |
| Graph | A diagram that shows how two variables are related. |
| Origin | The (0,0) point on a line graph. |
| Directly proportional | A term used to describethe relationship between two variables whose graph is a strait line passing through the point (0,0). If one goes up, the other goes up. If one goes down the other goes down. |
| Vary inversely | A term used to describe the relationship between two variables whose graph forms a curve that slopes downward. IF one goes up the other goes down. |
| Dry Ice | Name for frozen nitrogen gas. So solid changes directly to a gas without a liquid. Why? Because it is a frozen GAS. |
| universal gas law. | (Pressure x Volume) divided Temperature before a change is equal to (Pressure x Volume divided by Temperature after the change. |
| Temperature | Is the AVERAGE kinetic energy of a substance. |
| Thermal energy | Is the TOTAL energy of all the particles. |
| Heat | The transfer of thermal energy from a warmer object to a colder object is called ____. |
