Text Solution

AI Generated Solution

The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Statement**: The statement given is "Condensation of steam is not a chemical change." We need to determine if this statement is true or false. 2. **Defining Condensation**: Condensation is the process where a gas (in this case, steam, which is water vapor) changes into a liquid when it cools down. 3. **Identifying the Nature of the Change**: When steam condenses, it changes from a gaseous state (H2O gas) to a liquid state (H2O liquid). This change is a physical change, as it only involves a change in the state of matter and does not involve any alteration in the chemical composition of the substance. 4. **Differentiating Between Physical and Chemical Changes**: - A **physical change** is reversible and does not produce a new substance. For example, water can be turned back into steam by heating it. - A **chemical change**, on the other hand, results in the formation of a new substance and is usually irreversible. 5. **Conclusion**: Since condensation of steam is a physical change and does not produce a new substance, the statement "Condensation of steam is not a chemical change" is indeed true. **Final Answer**: True ---
