The Gibbs function of a thermodynamic system is defined by G H- TS. If the system is consisting of two phases 1 and 2 of a single substance and maintained at a constant temperature and pressure, the equilibriunm condition for the coexistence of these two phases is that the specific Gibbs functions are equal Consider now a first-order phase change between the phase 1 and the phase 2. At the phase boundary, the equilibrium condition for the...

The energy of radiation which is at thermal equilibrium within
an enclosure depends only on the volume of the enclosure and on the
wall temperature, T. It is also known that the pressure of Th q T c
q’ w 3 radiation is equal to one third of the energy per unit
volume. Show that the energy per unit volume, u , and entropy per
unit volume, s, of the radiation are given by

Problem 2. Phase volumes in a time-dependent two-phase continuous flow sys- tem. Consider a two-phase contacting vessel. In this problem, there are two immicscible liquid phases, but there is no solute mass transfer to be considered. Initially, the vessel contains a volume V = 25,000 L (25 m”) continuous phase (I), and no dispersed phase (II). At time zero, steady flows to the tank commence, with qf = 75 m3/hr and qf1 = 11 mº/hr. Flow exits the vessel via...

A closed system (gas molecules do not enter or leave the
cylinder) consists of a cylinder containing a gas, which has an
internal energy given by U = (5/2) n R T. The
initial pressure and volume are P0 and
V0, respectively. The pressure of the gas is
doubled while the volume remains constant (A→B), then its volume is
doubled while the pressure remains constant (B→C), then the
pressure is halved while the volume remains constant (C→D), and
finally the...

2) Partial Equilibrium Suppose there is an economy with only two consumers. Both have identical preferences: U(q, t) qVzt1/2. The first individual has an income of S3600, while the second agent has an income of S7200. The price of good t is fixed at a) Find the Marshallian demands for q for each type. (6 points) b) Find the market demand for q (remember P-1). (6 points) The market for q is perfectly competitive with many...
