QuestionAnswer
Circuit closed conducting loop through which an electric current can flow
Conductor material, such as copper wire, in which electrons can move easily
Electric Current the net movement of electric charges in a single direction, measured in amperes (A)
Insulator material in which heat flows slowly
Parallel Circuit circuit in which electric current has more than one path to follow
Series Circuit circuit in which electric current has only one path to follow
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 all 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 shape, 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. An increase in the volume of the container causes the pressure to drop, if the temperature remains constant.
Charles's Law the volume of a gas increases with increasing temperature, as long as pressure does not change. the reverse is also true
Pascal Principle pressure applied to a fluid is transmitted throughout the fluid
Bernoulli's Principle as the velocity of a fluid increases, the pressure exerted by the fluid decreases
Archimedes Principle The buoyant force on an object is equal to the 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
