Make a sketch of the Gibbs free energy, G, versus temperature, T, for a single component system as the temperature increases at a fixed pressure, P. Indicate the temperatures where the pure substance changes from liquid to solid, and from solid to gas, and comment on the slopes of the plot of G versus T.
The internal energy, U, is the total energy of a system. For any isolated system, the internal energy is constant. U is a state function, meaning that any path used in calculating AU ill result in the same answer. For any pure substance or fixed mixture of substances, the internal energy, U, can be determined from any two of the variablesP, V, and T. It is often most convenient to choose V and T as the variables. It is helpful,...
