| Question | Answer |
|---|---|
| Compressed | forced or closed together |
| Kinetic Theory of Matter | a theory that matter is made of atoms and molecules which act like tiny particles that are always in motion |
| Evaporation | the change of state from a liquid to a gas |
| Condensation | the change of state from a gas to a liquid |
| Boiling | the temperature at which a liquid boils |
| Vaporization | change of a liquid or solid substance to a gas |
| Solidification | change from a liquid or gaseous to a solid form |
| Sublimation | the process in which a solid changes directly into a gas. |
| Deposition | the process of changing of a gas to a solid without passing through an intermediate liquid phase |
| Melting | the temperature at which a solid changes into a liquid |
| Law of Conservation of Mass | mass cannot be created or destroyed |
| Law of Conservation of Energy | energy cannot be created or destroyed |
| Pressure | the amount of force exerted per unit area of a surface |
| Pascal | the SI unit of pressure; equal to the force of 1N of an exerted over an area of 1M squared. |
| Buoyant Force | the upward force that keeps on a object immersed in or floating on a fluid |
| Viscosity | the resistance of a gas or liquid to flow |
| Archimedes' Principle | the buoyant force on an object in a fluid is an upward force equal to the weight of the fluid that the object displaces |
| Pascal's Principle | a change in pressure at any point in an enclosed fluid will be transmitted equally to all parts of the fluid |
| Hydraulic Device | a device that uses pressure from one point to another |
| Bernoulli's Principle | as the speed of a moving fluid increases, the pressure of the moving fluids decreases |
| Gas Laws | the laws that state the mathematical relationships between the volume,temperature,pressure, and quantity, of a gas |
| Charles' Law | for a fixed amount of gas at a constant pressure, the volume of the gas increases as the gas's temperature increases. Likewise the volume of the gas decreases as the gas's temperature decreases |
| Boyle's Law | for a fixed amount of a gas at a constant temperature,the volume of a gas increases as the gas's pressure decreases. Likewise, the volume of a gas decreases as the gas's pressure increases |
| Gay-Lussac's Law | the pressure of a gas increases as the temperature increases, if the volume of the gas does not change. The pressure decreases if the temperature decreases |
| Freezing | the temperature at which a liquid changes into a solid |
