In an adiabatic container, two solid blocks, one hot and the other cold, are placed next to each other. After a while, thermal equilibrium is established due to heat transfer from the $($formerly$)$ hot block to the $($formerly$)$ cold block. According to the First Law, the energy lost by the hot block will be gained by the cold one. Does the Second Law require that the decrease in entropy of the hot block be equal to the increase in entropy of the cold one?
