2. (25 pts) Derive the (a) Maxwell relation for the Helmholtz Free Energy F=U-TS. Show ALL steps and justifications in your derivation. Using your result in (a) comment on how (b) the entropy behaves for an isothermal expansion of an ideal gas. Finally, show the validity of the following equations (c) U = F-TOOF) -T2 and at (T) 01 (d) C =-1(
Let S = V-1 (V/T)S be the isoentropic coefficient of thermal expansion. Use a Maxwell relation and the expansion, chain and inversion relationships to show that S = - CV/VT
9. In a free expansion of a perfect gas (also called Joule expansion), we know that internal energy U does not change, and no work is done. However, the entropy must increase because the process is irreversible. Are these statements compatible with the first law of thermodynamics
5. (25 points For credit; show every step in the derivations. (a) Starting with the Fundamental Equation for U determine the associated partial derivatives for T and P. Next, determine the associated Maxwell Relation. (b) Starting with the Helmholtz free energy (A = U – TS) derive the associated Fundamental Equation and identify the partial derivative relationships for P and S. Then derive the associated Maxwell Relation.

5. (a) Derive the following Maxwell relation for a fluid system: ()-), (b) Show that for an ideal gas at a given temperature T, the chemical potential difference between an arbitrary pressure, P, and a reference pressure, Po, is given by u(P) – u(Po) = kbT In (P/Po). (c) For the case of an incompressible liquid, the volume per particle, v = V/N, is independent of the pressure; show that in this case, one has u(P) – ”(Po) = v...
Part I: Derive the phasor relation for a capacitor starting from the equation that describes the current through a capacitor as a function of a voltage on a capacitor. Assume that the capacitance of the capacitor is C.
