Question

At temperatures below 0 °C, liquid water freezes spontaneously. What drives this process thermodynamically?
Options

B The heat released increases the entropy of the surroundings significantly
Correct Answer
C The molar volume of ice is less than that of liquid water
D Freezing is an endothermic phase transition
Correct Answer

Option B is the correct answer.
