1. Calculate the coefficient of volume expansion, j3, for a van der Waals gas in terms of p, v, a, and h.
2. Consider an ideal gas whose molecules have v degrees of freedom and which is undergoing some process that we are tracing on a p- V diagram. In terms ofp, V, and v, what is the slope of this path at the point (p, V) on the diagram if the process is
(a) isobaric,
(b) isothermal,
(c) adiabatic (pVY = constant, where y = (v + 2)/v)?
