One mole of an ideal paramagnetic gas obeys Curie's law, with a Curie constant Cc. Assume that the internal energy U is a function of T only, so that dU = Cy mdT, where Cy m (a) Show that the equation of the family of adiabatic surfaces is is a constant heat capacity. Cy m In T+ In V: nR + In A, 2n RCC where A is a constant for one surface. (b) Sketch one of these surfaces on a TVM diagram.
