If a billion children neaten their bedrooms, how much does the entropy of their toys and clothing decrease? Assume that they each have one hundred distinguishable items weighing 20gm, initially randomly placed in a bedroom with V=5m3 , and that they end up located in their place in a drawer with center-of-mass location accuracy of 1cm. For this exercise, assume that the internal entropies of the objects are unchanged in the process (atomic vibrations, folding entropy for socks, etc.) Compare this entropy change to that of contracting the air in a one liter balloon by 1% in volume.
