It's possible to find the constant \(b\) if you fit Debye's equation to some experimental measurements of … A pure perfect crystal is one in which every molecule is identical, and the molecular alignment is perfectly even throughout the substance. According to the third law, the reason that T=0 cannot be reached is explained as follows: Suppose the temperature of a substance can be reduced in an isentropic process by changing the parameter X from X2 to X1. Temperature, Heat and the First Law of Thermodynamics. If ΔS univ < 0, the process is nonspontaneous, and if ΔS univ = 0, the system is at equilibrium. The third law of thermodynamics is essentially a statement about the ability to create an absolute temperature scale, for which absolute zero is the point at which the internal energy of a solid is precisely 0. The Third Law of Thermodynamics means that as the temperature of a system approaches absolute zero, its entropy approaches a constant (for pure perfect crystals, this constant is zero).

The Third Law of Thermodynamics Statements of the Third Law In the cooling processes the lower the temperature attained, the more difficult it is to cool further. The Third Law of Thermodynamics means that as the temperature of a system approaches absolute zero, its entropy approaches a constant (for pure perfect crystals, this constant is zero). Third law: The entropy of a perfect crystal is zero when the temperature of the crystal is equal to absolute zero (0 K). Carath eodory’s and Gibbs’ approaches together allow to better de ne the problem of the third law.
