Definition: Werther's law is a fundamental principle in thermodynamics that describes the behavior of heat transfer between two different materials. It states that the amount of heat transferred from one material to another depends on the temperature difference between them, regardless of their initial conditions.
The formula for the thermal conductivity of a material can be expressed as:
λ = μ
k
T
Where λ is the thermal conductivity, μ is the thermal diffusivity, k is the thermal conductivity constant, and T is the temperature
