Teacher:In this task you will be given a text passage from a trivia quiz. You should choose the category this question belongs to from these categories: History, Science, Social Science, Fine Arts, Literature. You can only choose one category, so if in doubt, please choose the closest match.
Teacher: Now, understand the problem? Solve this instance: This quantity is plotted on the y axis against entropy in a Mollier diagram. The heat capacity at constant pressure is given by the derivative of this quantity with respect to temperature, and this quantity appears in the numerator divided by RT across from the derivative of the log of pressure with respect to temperature in the Clausius-Clapeyron equation. Joule-Thomson cooling occurs at a constant value of this quantity, which can be written as the derivative of the log of the partition function with respect to the inverse temperature. For ten points, identify this quantity which is used to calculate heat transfer, often across phases, and is defined as the internal energy plus the product of pressure and volume.
