WebMay 22, 2024 · Stefan–Boltzmann Law. Radiation heat transfer rate, q [W/m 2], from a body (e.g. a black body) to its surroundings is proportional to the fourth power of the absolute temperature and can be expressed by the following equation:. q = εσT 4. where σ is a fundamental physical constant called the Stefan–Boltzmann constant, which is equal to … WebSep 25, 2024 · When heat transfers from a hot Th to cold Tc reservoirs, entropy of cold reservoir increases by Q/Tc and entropy of hot reservoir decreases by Q/Th. Since Tc < Th, total change in entropy of the system (universe) > 0 ∆Su = Q / Tc – Q / Th > 0 Thus, if ∆Su < 0, process cannot occur (e.g. heat transfer from cold to hot body).
