9Sci CH8
9th Science CH8 Solids, Liquids, and Gases
| Term | Definition |
|---|---|
| Archimedes’ principle | the Greek mathematician Archimedes stated that the buoyant force on an object in a fluid is equal to the weight of the fluid displaced by the object |
| Bernoulli’s principle | the Swiss scientist Daniel Bernoulli stated that as the velocity of a fluid increases, the pressure exerted by the fluid decreases |
| Boyle’s law | British scientist Robert Boyle stated that the volume of a gas decreases when the pressure increases, provided the temperature stays the same |
| buoyant force | ability of a fluid to exert an upward force on an object immersed in the fluid |
| Charles’s law | French scientist Jacques Charles stated that the volume of a gas increases when temperature increases, provided the pressure stays the same |
| condensation | the change of a substance from a gas to a liquid, which usually takes place when a gas is cooled to or below its boiling point |
| crystal | in most solids, the arrangements of particles in repeating geometric patterns |
| evaporation | the gradual change of a substance from a liquid to a gas at temperatures below the boiling point |
| heat of fusion | the amount of energy needed to change a material from the solid state to the liquid state |
| heat of vaporization | the amount of energy needed to change a material from a liquid to a gas |
| kinetic theory of matter | the idea that all matter is made up of constantly moving, tiny particles |
| pascal | the SI unit of pressure; 1 pascal (Pa) of pressure = 1 newton/square meter |
| Pascal’s principle | French scientist Blaise Pascal stated that pressure applied to the fluid is transmitted unchanged through the fluid |
| plasma | a gas-like mixture of charged particles that exists at extremely high temperatures |
| polluted water | water that contains high levels of unwanted substances that may be harmful to living organisms |
| pressure | the amount of force exerted per unit of an area |
| states of matter | any of the four conditions in which matter can exist; solid, liquid, gas, or plasma; the state of a sample of matter depends on its temperature |
| thermal expansion | a characteristic of almost all matter that causes it to expand when heated and contract when cooled |
| thermal pollution | pollution caused when waste heat raises the temperature of the environment; thermal pollution in bodies of water can damage or destroy plants and animals that live there |
| Venturi effect | reduction in pressure of a fluid resulting from the speed increase as fluids are forced to flow faster through narrow spaces |
