You are collecting data from the literature on a compound, for which you need to know the specific internal energy at a number of different states. You’ve found some data from three different sources, but they each use different reference states and the units aren’t uniform either. The data is shown in the table below. Fill in all of the empty cells in the table, so that you have correct values of U ˆ for all seven condi-tions (A–G) at all three reference states.
