Q. Consider heat flow across a biological tissue layer that behaves according to Fourier's law (𝑱𝒒=−𝒌𝜵𝑻). If the tissue undergoes a physiological change such that its thermal conductivity (𝒌) doubles, but the temperature gradient (𝜵𝑻) across the tissue is reduced to half of its original value, how will the new heat flux (𝑱𝒒′) compare to the initial heat flux (𝑱𝒒)?
