Resumen de On cities and entropy: a thermodynamical view of the large towns

Nilo Costa Serpa

• Present article proposes the application of the concept of entropy in the study of the environmental impacts created by a city. It was taken a strictly thermodynamic approach of cities as heat sinks that generate entropy. The formalism of caloric field theory was adopted to establish the relationship between entropy caused by thermal exchanges and the physical environmental parameters considered. The notion of evolutional global time was introduced in order to treat entropy more objectively in the context of thermodynamics. A table with the rates of change of entropy in some cities was set.
