We shall see in Chapter 10, Section 10.4, if we can develop a more general expression for the difference in the heat capacities of any substance, not just an ideal gas. But

Calculus of Variations 1 Functional Derivatives The fundamental equation of the calculus of variations is the Euler-Lagrange equation d dt ∂f ∂x˙ − ∂f ∂x = 0. There are several ways to derive this result, and we will cover three of the most common approaches. Our ﬁrst method I think gives the most intuitive Maxwell's relations are a set of equations in thermodynamics which are derivable from the symmetry of second derivatives and from the definitions of the thermodynamic potentials. These relations are named for the nineteenth-century physicist James Clerk Maxwell Equations. The structure of Maxwell relations is a statement of equality among the second derivatives for continuous functions. It

08/09/2005 · How to Do Math Proofs. Mathematical proofs can be difficult, but can be conquered with the proper background knowledge of both mathematics and the format of a proof. Unfortunately, there is no quick and easy way to learn how to construct a... Starting from the fundamental definitions for Cp and Cv, show that for all ideal gases, Cp = Cv + R I haven't learnt about entropy yet. This question should be possible just using the First Law and pV = RT.

In general, Cp=Cv + a 2 TV/K T, where a is the expansion coefficient and K T is the isothermal compressibility. This equation is
