Fourier's Second Law is essential for analyzing transient temperature distributions in materials where thermal equilibrium has not yet been reached. This model utilizes the one-term approximation, which is valid for Fourier numbers greater than 0.2, to predict temperature profiles in industrial applications like curing and quenching.
