For this purpose, we assume a universe filled with dark fluid and consider five-dimensional (5D) field equations using the Gamma law equation. We mainly discuss the validity of the first and generalized second laws of galactic thermodynamics for viable Kaluza-Klein models.eninfo:eu-repo/semantics/closedAccessKaluza-Klein TheoryThermodynamicsEntropyDark EnergyArticle316WOS:0003711274000052-s2.0-8495891928410.1142/S0217732316500383Q2Q3
