As a subject matter expert in thermodynamics, I can provide a detailed explanation of the entropy changes that occur when water freezes.
Entropy is a measure of the randomness or disorder of a system. In the context of phase changes, it is important to consider the entropy of the entire system, which includes not only the water but also its surroundings. When water freezes, the process involves a decrease in the entropy of the water itself due to the formation of a more ordered crystalline structure. However, this decrease in entropy is not the whole story.
The process of freezing is exothermic, meaning it releases heat to the surroundings. This heat transfer increases the entropy of the surroundings, as the energy is dispersed over a larger number of microstates. The total entropy change of the universe, which is the sum of the entropy changes of the system and its surroundings, can be positive, negative, or zero. In the case of water freezing, the increase in entropy of the surroundings can be greater than the decrease in entropy of the water, leading to an overall increase in the universe's entropy.
This is in line with the second law of thermodynamics, which states that the total entropy of an isolated system can never decrease over time; it can only increase or remain constant. The formation of ice is a spontaneous process at temperatures below the freezing point, indicating that the total entropy of the universe increases during this process.
The concept of entropy is closely related to the number of microstates available to a system. In the liquid state, water molecules have more freedom to move around and can occupy a greater number of microstates compared to the solid state. When water freezes, the molecules become locked into a rigid lattice, reducing the number of available microstates and thus decreasing the entropy of the water. However, the release of latent heat during freezing compensates for this decrease, contributing to the overall increase in entropy of the universe.
In summary, while the entropy of water decreases as it transitions from a liquid to a solid state, the total entropy of the universe increases due to the heat released into the environment and the increased entropy of the surroundings. This is consistent with the principles of thermodynamics and the behavior of spontaneous processes in nature.

We've said as an example, that the entropy of water increases when it melts, and decreases when it freezes. But we know that ice happens! The key here is the word "universe". Entropy can decrease in some things, provided it increases in others.
