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. |
