|---|---|
| closed conducting loop through which an electric current can flow through | circuit |
| material such as copper wire,i which electrons can move easily. | conductor |
| the net movemnet ofelecric charges in a single direction measure in amperes. | electirc current |
| material in which electrons are not albe to move easily | insulator |
| circuit in which electric current has more than one path to follow | parallel circuit |
| cirucit in which elecrict current has only one path to follow. | series cirucit |
| electric current that reverse its direction of flow in a regular pattern. | alternating current |
| electric current that flows in only one direcction. | direct current |
| change of one substance into a new substance. | chemical change |
| any characteristic of a substanc,such as flammability that indicates whether it can undergo a certain chemical change. | chemical properties |
| susbstance formed from two ro more elements in which the exact combination and proportion of elements is always the same. | compound |
| susbstance with atoms that are all alike. | element |
| any change in size,shape or state of matter in which the identity of the substance remains the smae. | physical change |
| any characteristic of a material such as size or shape,that you can observe or attempt to observe without changing the identity of the material. | physicla properties |
| if you decrease the volume of a container of gas and hold the temp at constant the presssure of the gas will increase. | boyeles law |
| the volume of a gas increases with increasing temp as long as pressure does not change. | charles law |
| pressure applied to a fluid is transmitted throughout the fluid. | pascal principle |
| as the velocity of a fluid increases the pressure exerted by the fluid decreases. | bernoulili's principle |
| the buoyant force on an object is equal to the weight ofthe fluid displaced by the object. | archimedes principle |
| explanation of how particles in matter behave. | kinetic theory |
