• B. Both physical and chemical change
• C. Chemical change
• D. Neither physical nor chemical change

Answer: (A)

Verified step by step guidance

1. Understand the definitions: A physical change affects the form of a substance but not its chemical composition, while a chemical change results in the formation of one or more new substances with different chemical properties.
2. Consider the process of evaporation: When water evaporates, it changes from liquid to gas (water vapor), which is a change in its physical state.
3. Analyze whether the chemical composition changes: During evaporation, water molecules (H\_2O) remain chemically the same; no new substances are formed.
4. Conclude that since only the physical state changes and the chemical identity remains constant, evaporation is a physical change.
5. Therefore, the correct classification for water evaporating from a surface is a physical change.
