| Question | Answer |
|---|---|
| Fluids | Any non-solid state of matter in which particles can move past one another. |
| plasma | a state of matter that starts as a gas and then becomes ionized |
| energy | the capacity to do work |
| thermal energy | the kinetic energy of a substance's atoms |
| evaperation | the change of state from a liquid to a gas |
| sublimation | the process in which a solid changes directly into a gas |
| condensation | the change of state from a gas to a liquid |
| fluid | a nonsolid state of matter in which the atoms or molecules are free to move past each other, as in a gas or liquid |
| buoyant force | the upward force that keeps an object immersed in or floating on a liquid |
| pressure | the amount of force exerted per unit area of a surface |
| Archimedes' Principle | the principle that states that the buoyant force on an object in a fluid is an upward force equal to the weight of the volume of fluid that the object displaces |
| pascal | the SI unit of pressure; equal to the force of 1 N exerted over an area of 1 m2 (symbol, Pa) |
| Pascal's Principle | the principle that states that a fluid in equilibrium contained in a vessel exerts a pressure of equal intensity in all directions |
| viscosity | the resistance of a gas or liquid to flow |
| Boyle's Law | the law that states that for a fixed amount of gas at a constant temperature, the volume of the gas increases as the pressure of the gas decreases and the volume of the gas decreases as the pressure of the gas increases |
| Charles' Law | the law that states that for a fixed amount of gas at a constant pressure, the volume of the gas increases as the temperature of the gas increases and the volume of the gas decreases as the temperature of the gas decreases |
| Gay-Lussac's Law | the law that states that the volume occupied by a gas at a constant pressure is directly proportional to the absolute temperature |
