The entropy of water is greater than that of ice, so whether the process of water freezing violates the second law of thermodynamics, please explain it to the expert.

Entropy increases because for isolated systems,

The process of water freezing can be roughly divided into three categories.

1, you cooled the water supply ... there is external energy ... it is not an isolated system, and the entropy can be completely reduced.

2. Water is in an isolated system, and there are other substances in this system. The entropy of water decreases, but with the freezing and heat release of water, the entropy of other substances increases and the system increases.

3. Water is in an isolated system, and there is only water in this system-hahahaha, if you put water in a vacuum, it will not interact with any other substance, nor will it freeze, but will spread ~

If it's practical, that's it

If you have passed the college entrance examination, are interested in nature and are not satisfied with pragmatism, I can tell you a good news that the second law of thermodynamics is actually wrong! Just like Newtonian mechanics is not truth, but it is very useful in engineering.
