When a group of atoms can form two or more stable configurations, the energy of vibrations needed for this group of atoms to change from a certain configuration to another is also called the activation energy. Activation energy can be determined by the temperature dependence of a property whose value is directly connected with surpassing potential barriers by atoms or ions of glass. These are the so-called transport properties.</rdfs:comment> <metadata_def:mappingLoom>activationenergy</metadata_def:mappingLoom> <metadata_def:mappingSameURI rdf:resource="https://glasdigi.cms.uni-jena.de/glass/ActivationEnergy"/> <metadata_def:prefLabel xml:lang="en">activation energy</metadata_def:prefLabel> <metadata:prefixIRI>glass:ActivationEnergy</metadata:prefixIRI> <obo_purl:IAO_0000119 xml:lang="en">SciGlass 7.0</obo_purl:IAO_0000119> </owl:Class> <rdf:Description rdf:about="https://glasdigi.cms.uni-jena.de/glass/ActivationEnergy"> <metadata_def:mappingSameURI rdf:resource="https://glasdigi.cms.uni-jena.de/glass/ActivationEnergy"/> </rdf:Description> </rdf:RDF>
