Using some ideas of Modern Kaluza-Klein theory, we examine the evolution of entropy on a 4D Friedmann-Robertson-Walker (FRW) brane from a 5D vacuum state, which is defined on a 5D background Riemann-flat metric. We found that entropy production is sufficiently important during inflation: S > 1090, for all the initial values of temperature T0 < TGU. the initial values of temperature T0 < TGU. S > 1090, for all the initial values of temperature T0 < TGU.T0 < TGU.
