| Question |
Answer |
| Archimedes' principle | The buoyant force exerted on a body in a fluid is equal to the weight of the fluid displaced. |
| barometer | A device used to measure atmospheric pressure. |
| Bernoulli's principle | States that the pressure of a fluid decreases as its speed increases. |
| Boyle's law | The volume of a dry gas is inversely proportional to the pressure it exerts, if the temperature remains constant. |
| Charles's law | The volume of a gas at constant pressure is directly proportional to its Kelvin temperature. |
| fluid mechanics | The study of fluid movement and forces. |
| fluids | Liquid or gas phases of matter. |
| hydraulic machines | Machines which use fluid to transmit or increase force. |
| pascal (Pa) | Unit of pressure equal to one Newton of force over a square meter (N/mxm). |
| Pascal's principle | Changes in pressure in a confined fluid are distributed equally in all directions throughout the fluid. |
| pressure | The force pushing directly on a given surface. |
