    the molecule /object having more entropy s1 is more disorder and random,not stable

    Entropy is a fundamental term in physics. It is not very intuitive so all the more reason to think about it as much as deeply as possible so as to ingrain it in your head... A measure of entropy is a measure of disorder. For example, take a set number of molecules of water at room temperature. The water is liquid because of the arrangement of these molecules of water. Now, add heat and the molecules will begin to vibrate violently and separate from each other and this is the point where water would begin to boil off. We can say that water in gaseous state has more entropy than water in liquid state because the molecules are more disorderly and random. So working AGAINST entropy takes a lot of energy. The point of all of this is that in general, the processes that result in a higher state of entropy, are more prone to be spontaneous than those that are not. That is because disorder into order takes much energy. An analogy... it takes a lot of energy (a whole police armada) to bring only a handful of criminals into justice.
