摘要We calculate the work made out by the apparent horizon (AH) of the Friedmann-Robertson-Walker (FRW) universe and the heat flux through the AH from the first law of thermodynamics. We discuss the mechanical properties of the AH and analyze the universe model for which the mechanical properties can change. Finally, the thermal properties of the AH of FRW universe are discussed.
