Q. Consider the following statements regarding thermodynamic forces, fluxes, and entropy production in biological/open systems:
P. Thermodynamic forces represent the driving tendency for a process to occur.
Q. For any spontaneous, irreversible process, the entropy production rate satisfies 𝝈≥𝟎.
R. At thermodynamic equilibrium, thermodynamic fluxes become maximal while entropy production drops to zero.
S. A non-zero thermodynamic flux driven by its conjugate force leads to continuous entropy production in irreversible processes.

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)?
