1. Thermal Conduction

Thermal conduction is the transfer of heat energy through an object or from one object to an adjacent object. It is caused by the transfer and dissipation of kinetic energy from one atom to surrounding atoms when the atoms are in close proximity, such as in a solid or liquid. An example is putting a spoon in a cup of hot tea - the handle of the spoon becomes warm even though the handle itself is not in direct contact with the tea. Heat has been conducted from the tea into the scoop end of the spoon, and then though the spoon up to the handle.

Conduction can occur between substances (as in from hot tea to a spoon) or within a single substance (as in dissipate down the length of the spoon).

Iron (Fe) is an example of a good thermal conductor. Heat can transfer through an iron object quickly.

2. Electrical Conduction

Electrical conduction is the flow of free electrons through a substance with very low impedance (resistance) to the movement of those electrons. The uniform flow of electrons gives rise to the movement of electric charge, creating an electric current. In electrical conduction, free electrons pass through the conducting material without changing the ionic balance (the charge) of the conducting substance's atoms and/or molecules.

Copper (Cu) is an example of an electrical conductor, that allows free electrons to pass through a copper cable with minimal impedance.

One definition of the word conduction is "the process by which sound waves travel through a medium."

It obviously has to be conduction, as the definition of conduction is, " the transfer of energy through a medium.", the oil being the medium transferring the (thermal) energy.

Conduction is a mode of transfer of energy within and between bodies of matter, due to a temperature gradient.

Conduction is the transfer of heat between two parts of a stationary system, caused by a temperature difference between the parts.

Conduction is a phenomenon not a material.

I think you might mean conduction.Conduction can transfer heat from one part of an object to another.We studied conduction in physics class.

electrical/electronic definition: a material with low electrical resistance at standard temperature and pressure.solid state physics definition: a material with many electrons occupying conduction band energy levels at standard temperature and pressure. these conduction band electrons form an "electron gas" which fills the bulk of the material and like a real gas readily flows through the material.

the opposite of conduction is insulation. Your question needs to be referenced to what you are talking about as conduction is a multi use word.

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

Conduction can cause a spark which can light a light bulb. Conduction can be used to heat up metals.

It is used for CONDUCTION because conduction is when the two materials are touching and in the instance of ironing something they are touching so it is CONDUCTION :))))

Two examples of heat conduction that are observable in everyday life:- heat conduction through walls- heat conduction through clothing- heat conduction from many home appliances

conduction can tell you what its going to be that day
