Thermodynamics: Heat - Work

This lecture covers the different forms of energy exchanged, including ordered and disordered forms, as well as the variation in the degree of internal molecular agitation. It explains the universally adopted customs convention in thermodynamics and the concept of work exchanges, defining work as the elemental work for finite displacement. The lecture also delves into the work of gas expansion, generalizing the expression of exchanged work with various applications. Furthermore, it discusses heat exchanges, defining heat as the energy exchanged between a system and the external environment due to temperature differences, and categorizes heat into sensible and latent heat. The instructor concludes by presenting the program 'MOOCs for Africa' developed by EPFL in collaboration with various partners for the enhancement of higher education in Africa.
