Explain the third law of thermodynamics
WebThe third law of thermodynamics states that a system's entropy approaches a constant value as the temperature approaches absolute zero. With the exception of non-crystalline solids , the entropy of a system at absolute zero is typically close to zero. The first ... WebNov 5, 2024 · The third law of thermodynamics provides an absolute reference point for the determination of entropy. The entropy determined relative to this point is the absolute entropy. Absolute entropy can be written as S = k B \logW, where W is the number of available microstates. Since at T = 0 there is no entropy difference, an infinite number of …
