Liquid water freezing to crystalline ice is an example of a system going to a state with a higher degree?

Question

of order. Which of the following is the best explanation of how this process can be compatible with the Second Law of Thermodynamics?

Answer choices:
1. Heat is flowing out of the system reversibly, so it is allowed.
2. A higher degree of order means an increase in entropy, which is exactly what the Second Law requires.
3. The surroundings are undergoing changes in the direction of greater disorder.
4. Since no chemical change is taking place, the degree of order is not relevant.
5. Since the process is not occurring at 0 Kelvin, the Second Law is not relevant.

Answer 1

I think (3) is the correct answer. It makes the most sense. The formation of a solid (ice) from liquid (water) represents a decrease in entropy. This is NOT a spontaneous process. So, I think to counter this, the surroundings have to be undergoing a greater increase in entropy.

Answer 2

1 seems me correct. Change of phases is a reversible process
