Verified step by step guidance

Understand the concept of entropy: Entropy is a measure of the disorder or randomness in a system. In general, the more disordered a system, the higher its entropy.

Consider the states of water: Solid ice has a structured, ordered lattice structure, while liquid water has molecules that are more free to move around, leading to a less ordered state.

Analyze the phase change: When ice melts to form liquid water, the structured arrangement of molecules in the solid state becomes more disordered as they move into the liquid state.

Relate phase change to entropy: Since the transition from solid to liquid involves an increase in disorder, the entropy of the system increases.

Conclude based on the analysis: Therefore, when solid ice melts to liquid water, the entropy of the system increases.
