Chapter 16 Review
| Term | Definition |
|---|---|
| Boiling Point | Temperature at which pressure of liquid's vapor equals external pressure. |
| Buoyancy | Ability of a liquid to exert an upward force on an object. |
| Diffusion | Spreading of particles until equally distributed. |
| Heat of Fusion | Amount of energy required for a solid to change into a liquid. |
| Heat of Vaporization | Amount of energy required for a liquid to change into a gas. |
| Kinetic Theory | Explains that all matter is composed of small particles, have space between them, and collide with each other. |
| Pascal | Unit of pressure. |
| Plasma | Matter consisting of positive and negative particles. |
| Thermal Expansion | Increase in size of substance when temperature increases. |
| Viscosity | Resistance to flow. |
| Boyle's Law | If volume decreases, pressure increases. |
| Charles's Law | If volume increases, temperature increases. |
| Archimedes' Principle | Buoyant force on object is equal to weight of the fluid object displaces. |
| Pascal's Principle | Pressure applied to a fluid is unchanged throughout fluid. |
| Bernoulli's Principle | If velocity increases, pressure decreases. |
