Using the ideal gas equation of state, verify (a) the cyclic relation and (b) the reciprocity relation at constant P.

Define points P1-P6 in the diagram.

Consider a system consisting of three quanta of energy distributed between four molecules. Each molecule may possess three, two, one or no quanta. (a) Show, by drawing the various possible arrangements, that there are 20 different ways of distributing the quanta between the molecules. (b) Use theBoltzmann formula to calculate the entropy of the system.

The discipline dealing with material distribution between coexisting phases is called Select one: O a. Fluid dynamics O b. Physical chemistry O c. Civil engineering O d. Phase-equilibrium thermodynamics
