Thermal Conductivity: Definition, Units, Equation & Example
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. Consider the tile floor in the example in the beginning. It is a better conductor than the carpet. You can tell just by feel.
