a conductor is

• a substance or object that allows energy (such as heat or electricity) to move through it efficiently. Examples include copper and steel.

• the process in which the hotter parts of a gas or liquid rise to the top and the cooler, denser parts sink.

• tightly packed in.

• the ability to do work, have power or produce change.
