WebSep 5, 2024 · The heat in this equation refers to the reversible heat pathway only, (side note: "δ" sign means path function differential, "d" sign means state function differential). Entropy is a state function because it only refers to one and only one path for the heat, the reversible pathway. There is no other pathway, so it becomes a state function.

WebSep 9, 2024 · What is the increase of entropy? Assume that the specific heat capacity of water is C = 4184 J kg −1 K −1, that it does not vary significantly through the temperature range of the question, and that the water does not expand significantly, so that no significant amount of work (reversible or irreversible) is done. Solution indiana middle school wrestling 2023WebNov 19, 2024 · You define entropy as S = ∫ δ Q T. Clearly, T is an intensive quantity, as is 1 T. If δ Q is extensive, then so is δ Q T, since a product of an intensive and an extensive quantity is extensive. So, if δ Q is extensive, then ∫ δ Q T, being a sum of extensive quantities, is extensive. But you don't see why δ Q should be extensive. indiana midterm election 2022WebEthanol - Specific Heat vs. Temperature and Pressure - Online calculators, figures and tables showing specific heat , Cp and Cv, of gasous and liquid ethanol at temperatures ranging from -25 to 325 °C (-10 to 620 °F) at atmospheric and higher pressure - … indiana midterm elections
