What is conduction conduction?

There are two kinds of conduction: thermal conduction and electrical conduction.

  1. In thermal conduction, thermal energy (heat) transfers through a substance from a hotter region toward a cooler region. For example, when you dip a metal spoon into a cup of tea, the heat from the hot tea will conduct along the spoon so that the handle becomes warm, even though the handle is not in direct contact with the hot tea.
  2. In electrical conduction, free electrons pass through a substance, thus enabling an electric current.

Some materials are better conductors than others. Most metals are good thermal conductors, and certain metals (copper, aluminum) are very good electrical conductors. When a material is an exceptionally poor conductor, we call it an insulator. Styrofoam is a good thermal insulator, and glass is a good electrical insulator.

no, conduction describes how the heat is transported not how it is generated. With conduction, a heat source is still needed.

What test compares bone conduction and air conduction of sound using a turning fork?

The Rinne test compares bone conduction and air conduction of sound using a tuning fork. The tuning fork is initially placed on the mastoid bone behind the ear to assess bone conduction, then placed near the ear canal to assess air conduction. A normal result is when air conduction is greater than bone conduction.
