AB
Atomic MassThe average mass of one atom of an element,
Chain ReactionA multistage nuclear reaction, especially a self-sustaining series of fissions in which the release of neutrons from the splitting of one atom leads to the splitting of others.,
ConductionThe transfer of heat between two parts of a stationary system, caused by a temperature difference between the parts.,
Electric ChargeIs a physical quantity of matter which causes it to experience a force when near other electrically charged matter.Either positive or negative,
EsterAn chemical compound made by chemically combining an alcohol and an organic acid.,
Gravitational Potential EnergyPotential energy that depends on the height of an object.,
InertiaThe tendency of a body to resist acceleration; the tendency of a body at rest to remain at rest or of a body in straight line motion to stay in motion in a straight line unless acted on by an outside force.,
Laws of MotionThe three laws proposed by Sir Isaac Newton to define the concept of a force and describe motion, used as the basis of classical mechanics.,
MetalloidAn element that has some of the characteristics of metals and some of the characteristics of nonmetals,
Ohm’s LawThe current through a conductor between two points is directly proportional to the potential difference or voltage across the two points, and inversely proportional to the resistance between them.,
PolymerLarge, complex molecule built from smaller molecules bonded together.,
ResonanceTerm in chemistry used to explain properties of the octet rule when a single Lewis structure is inadequate.,
State of MatterThe three forms (liquid, solid, gas) in which matter exists,
TransformerAn electrical device by which alternating current of one voltage is changed to another voltage,
Weak BaseA chemical base that does not ionize fully in an aqueous solution. Ammonia is an example of a weak base.,
