In class, I told you that heat capacities are path dependent quantities. That is why we have Cy and a Cp heat capacities for example. It can be shown that the heat capacity along any path is given by Ст m aUm av T + P where Cm is the molar heat capacity along the path and Cv.m the molar heat capacity at constant volume. The dV/dT term can be evaluated from the equation that relates V and T along the given path. One mole of an ideal gas is heated reversibly along a path such that T-AV² where A is a constant. If the initial temperature is 240.3 K, what must be final temperature in K for the change in entropy of the system to be 19.687 J K-¹?
