Suppose a lot of papers are strewn al5 n;4-nmc/sf6ogxjq u jew1m3 l over the floor; then yo 4ju0qohx)b r;u stack them neatly. Does this violate the second law of thermodynamics? Eqo4urj)b ; 0xhxplain.
参考答案:
While
the state of the papers has gone from disorder to order, they did not do so
spontaneously. An outside source (you)
caused the increase in order. You had to
provide energy to do this (through your metabolic processes), and in doing so,
your entropy increased more than the entropy of the papers decreased. The overall effect is that the entropy of the
universe increased, satisfying the second law of thermodynamics.
