Thermal conductivity, the ability of a substance to conduct heat or move heat from one location to another without the movement of the material conducting the heat. Thermal conductivity is measured in watts per meter kelvin (W/mK). For example, solid aluminum has a thermal conductivity of 237 W/mK.
Thermal conduction is defined as the transport of energy due to random molecular motion across a temperature gradient. It is distinguished from energy transport by convection and molecular work in that it does not involve macroscopic flows or work-performing internal stresses.

A thermal conductor is a material that allows heat to flow easily through it. It has high thermal conductivity, meaning it can quickly transfer heat from one point to another. Examples of thermal conductors include metals like copper and aluminum. On the other hand, a thermal insulator is a material that restricts the flow of heat.
Materials that are good conductors of thermal energy are called thermal conductors. Metals are especially good thermal conductors because they have freely moving electrons that can transfer thermal energy quickly and easily.
Thermal conduction - a change in temperature due to particles passing on their motion through their bonds or by particle collisions. Thermal conductor - a substance along which thermal conduction happens quickly. Thermal insulator - a substance along which thermal conduction happens slowly
Definition of Thermal Conductivity Thermal conductivity is a measure of how easily heat energy moves through a material or how well that material can transfer heat. How well heat conduction occurs depends on the thermal properties of the material.
