State whether the following statements are true or false. In case a statement is false, write the corrected statement in your notebook
Formation of manure from leaves is a physical change. (True/ False)

Explanation

**Step-by-Step Solution:**

1. **Understanding the Statement**: The statement provided is "Formation of manure from leaves is a physical change." We need to determine if this statement is true or false.

2. **Defining Physical and Chemical Changes**:
- A **physical change** is a change that affects one or more physical properties of a substance but does not change its chemical composition. Examples include changes in state (like melting or freezing) or changes in size or shape.
- A **chemical change**, on the other hand, involves a change in the chemical composition of a substance, resulting in the formation of one or more new substances. This change is usually irreversible.

3. **Analyzing the Process**: The formation of manure from leaves involves the decomposition of organic matter. During this process, the leaves undergo a series of chemical reactions that transform them into manure.

4. **Determining the Nature of the Change**: Since the leaves are transformed into a completely different substance (manure) and cannot be reverted back to their original form, this indicates that a chemical change has occurred.

5. **Conclusion**: Therefore, the statement "Formation of manure from leaves is a physical change" is **false**. The correct statement should be: "Formation of manure from leaves is a chemical change."

**Final Answer**:
- The statement is **false**.
- Corrected statement: "Formation of manure from leaves is a chemical change."
