Physical Science
| Term | Definition |
|---|---|
| Pascal's Principle | A change in pressure at any point in an enclosed fluid will be transmitted equally to all parts of the fluid. |
| Ionized | Particles in plasma that are electrically charged. |
| Kinetic Theory of Matter | Matter is made up of atoms and molecules. |
| Gas Laws | The mathematical relationships between the volume, temperature, pressure, and quantity of a gas. |
| Viscosity | The resistance of a gas or liquid to flow. |
| Buoyant Force | The upward force that keeps an object immersed in or floating on a fluid. |
| Pascal | The SI unit of pressure; equal to the force of 1N exerted over an area of 1m(squared) (Symbol, Pa). |
| Pressure | The amount of force exerted per unit area of a surface. |
| Condensation | The change of state from a gas to a liquid. |
| Sublimation | The process in which a solid changes directly into a gas. |
| Evaporation | The change of state from a liquid to a gas. |
| Thermal Energy | The energy of a body arising from the motion of its atom or molecules. |
| Temperature | The total kinetic energy of a substance's atoms. |
| Energy | The capacity to do work. |
| Plasma | A state of matter that consists of free-moving ions and electrons. |
| 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. |
