Recall that thermal energy is an internal energy that consists of the kinetic and potential energies associated with the random motions of the atoms, molecules, and other microscopic bodies within an object.)
I thought internal energy $Q-W$ depends only on temperature (ignoring phase changes) and that the potential energy/bond dissociation energies are irrelevant in thermodynamics. They are useful in chemistry/QM. Perhaps my textbook meant gravitational potential energy. Has anyone know seen this before?
