| fluid | a material that flows ( gases & liquids) |
| Pressure | F / A |
| Pascal | Unit of pressure (Pa) |
| gas | takes shape of the container |
| liquid | fixed volume takes shape of container |
| solid | fixed volume and fixed shape |
| Pascals prinicple | Presure transmitted throughout a fluid is undiminished |
| Bournoulli's principle | Pressure exerted by a fluid dereases as the velocity of the fluid increases |
| Bouyant force | total upward force on an immersed object |
| Archimedes principle | bouyant force on an object is equal to the weight of the displaced fluid |
| Evaporation | Occurs when the most energetic paticles in a liquid have enough energy to escape into the gas phase |
| Volatile liquids | Have weak cohesive forces and evaporate quickly |
| Attractive forces that like particles exert on one another | Cohesive forces |
| Plasma | 4th state of matter made up of a mixture of positive and negative particles |
| 5th state of matter | Einstein-Bose state of matter |
| length of a material increases directly | If temperature increases |
| Change in length varies with ______ as well as temperature and length | type of material |
| Evaporation | cooling process (why?) |
| Bimetallic strips | expand at different rates and cause a bending of the metal |
