We focus attention on the particular thermodynamic relation dU ¼ T dS þ dW. Using information theory concepts we show that, for a reversible process in which intensive variables change, microscopic considerations related to this thermodynamic relation make the informational contents of, respectively, dU ¼ T dS þ dW and MaxEnt equivalent. The pertinent demonstration is obtained when trying to ascertain the corresponding equilibrium microscopic probability distribution.U ¼ T dS þ dW.
