SUMMARY
The discussion centers on the concept of internal energy in thermodynamics, specifically the equation U = q + W. Participants confirm that W represents the total work done, not limited to pressure work alone. The conversation highlights the inclusion of other forms of work, such as electrical work, particularly in the context of batteries and fuel cells. The equation is further elaborated with the formulation W = -P dV + W_other, emphasizing the need to consider various work types in thermodynamic calculations.
