| Question | Answer |
|---|---|
| circuit | closed conducting loop through which an electric current can flow |
| conductor | a material in which electrons are able to move easily |
| Electric Current | The net movement of electric charges in a single direction |
| Insulator | a material in which electrons are not able to move easily |
| Parallel Circuit | contains two or more branches for current to move through |
| Series Circuit | current has only one loop to flow through |
| Alternating Current | electric current that reverses its direction of flow in a regular pattern |
| Direct current | electric current that flows in only one direction |
| Chemical change | change of one substance into a new substance |
| chemical properties | any characteristic of a substance such as flammability, that indicates whether it can undergo a certain chemical change |
| compound | substance formed from two or more elements in which the exact combination and proportion of elements is always the same |
| element | substance with atoms that are alike |
| physical change | any change in size,shape, or state of matter in which the identity of the substance remains the same |
| physical properties | any characteristic of a material, such as size or shop , that you can observe or attempt to observe without changing the identity of the material |
| Boyle's law | if you decrease the volume of a container of gas and hold the temperature constant the pressure of the gas will increase |
| Charles law | the volume of a gas increases with increasing temperature as long as pressure does not change |
| Pascals principle | pressure applied to a fluid is transmitted throughout the fluid |
| bernoulli's principle | as the velocity of the fluid increases the pressure exerted by the fluid decreases |
| Archimedes principle | found the buoyant force on an object is equal to weight of the fluid displaced by the object |
| Kinetic Theory | explanation of the behavior of molecules in matter; states that all matter is made of constantly moving particles that collide without losing energy |
