| Question | Answer |
|---|---|
| A nonsolid state of matter in which the atoms or molecules are free to move past each other | fluid |
| matter with enough energy to overcome the active forces within its atoms positively and negatively charged particles | plasma |
| the ability to change; measured in joules | energy |
| measure of the average kinetic energy of all the particles that make up an object | temperature |
| sum of the kinetic and potential energy of the particles that make up an object | thermal energy |
| process where liquid turns into gas | evaporation |
| process of a solid changing directly to a vapor without forming a liquid | sublimation |
| gas to liquid | condensation |
| amount of force exerted per unit of area; SI unit pascal | pressure |
| ability of a fluid to exert an upward force on an object immersed in it | buoyancy |
| fluid's resistance to flowing; ex: honey = high; water = low | viscosity |
| the laws that state the mathematical relationships between the volume, temperature, pressure and quantity of a gas | gas law |
| temperature stays the same, volume increases, as gas pressure decreases | Boyle's law |
| pressure stays the same, volume increases, as temperature increases | Charles' law |
| volume stays the same, pressure of gas increases, as temperature increases | Gay-Lussac's law |
| SI unit for energy | joules |
| SI unit for pressure | pascal |
