Clausis inequality refrigeration
WebThis inequality when rearranged becomes: $$TdS-dq\ge0$$ For constant volume or pressure it becomes (recall $q_v=U,q_p=H$): $$TdS-U\ge0\\TdS-H\ge0$$ both of which say the common equations, (for a spontaneous change): $$dA=U-TdS\le0\\dG=H-TdS\le0$$ Share Improve this answer Follow answered Nov 20, 2014 at 12:00 RE60K 3,838 3 20 … WebApr 7, 2024 · Thus, the observation that heat never flows spontaneously from a colder region to a hotter region (the Clausius form of the second law of thermodynamics) is equivalent to requiring the net entropy change to be positive for a spontaneous flow of heat. If T1 = T2, then the reservoirs are in equilibrium and Δ S = 0.

WebAfter deriving Clausius inequality for all cycles: (1) ∑ i = 1 n Q i T i ⩽ 0 I've seen some books (Fermi, Thermodynamics is an example) doing what follows: If the cycle is reversible, we can consider the inverse cycle, and the only difference will be the opposite sign of the heats. So: (2) ∑ i = 1 n − Q i T i ⩽ 0 ∑ i = 1 n Q i T i ⩾ 0 WebClausius inequality was given for a thermodynamic cycle. It can be extended into the noncyclic process of a closed thermodynamic system. In the case of the first law of …
