(2) with respect to time. (a) Consider any measurement, such as total energy, that is expected to be constant What is the expected numerical value of the slope of a plot of total energy vs. time? If there is positive external work done during the trial, what is the expected slope? (You don't have enough information to give a specific number; be qualitative, for example, by comparing it to the previous part.) Repeat question (2b) but in the case of negative external work done during the trial. (b) (c)

Helmholtz Free Energy

The Helmholtz free energy is a thermodynamic potential used to calculate the measure of useful work from a closed system. This system is kept at constant temperature and volume. German physicist Hermann Helmholtz introduced this concept in 1882.
