I'm having a problem understand entropy. From my book, it says the following:
There is an example that says that
What I don't understand is if there is an increase in entropy, which is the increase in disorder, why does the hot water cool spontaneously when cooling the water makes the water molecules's movements more predictable, and move around slower, and eventually freeze into an ordered tetrahedral lattice in ice? To me, ice seems to have lesser disorder than liquid!
Thanks for any help!
It is a measure of the extent of disorder in a system or of the probability of the arrangement of parts of a system. Greater probability implies greater disorder and higher entropy.
There is an example that says that
In any isolated physical system the direction of spontaneous change is always from molecular order to disorder. A container of hot water, for example, undergoes spontaneous cooling as the energy of motion of its microscopic particles decreases
