A toy-model is used for describing the steps achieving the no-reversibledirection axiom in a tutorial manner: i) choice of a state space results in the balance equations on state space which are linear in the process directions, ii) a reversible process direction cannot be generated by combination of non-reversible ones, iii) process directions which are in the kernel of the balance equations do not enter the entropy production. The Coleman-Mizel formulation of the second law and the Liu relations follow immediately.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
