Answer

To determine whether the statement "The process of water changing into its vapour is called evaporation" is true, we can follow these steps:

### Step-by-Step Solution:

- In this case, we are looking at water, which is a liquid. When water changes from its liquid state to a vapor state, it is undergoing evaporation.

3. **Analyze the Statement**:
- The statement in question is: "The process of water changing into its vapour is called evaporation."
- Since we have established that when water (liquid) changes into vapor (gas), it is indeed called evaporation, we can analyze the truth of the statement.

4. **Conclusion**:
- Since the definition of evaporation matches the process described in the statement, we conclude that the statement is true.

### Final Answer:
