The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Changes:** - Changes occur all around us and can be observed in various forms. These changes can be physical or chemical in nature. 2. **Identifying Interaction:** - Almost all changes involve some form of interaction between two or more materials. This means that when a change happens, it often requires the involvement of different substances or objects that influence each other. 3. **Example of Water:** - A clear example of this interaction is the behavior of water. - When heat energy is added to water, it absorbs this energy and changes from liquid to gas, forming steam. This is a physical change due to the interaction of water with heat. 4. **Reverse Process:** - Conversely, if heat energy is removed from water, it loses energy and can change from liquid to solid, forming ice. This again illustrates the interaction between water and energy. 5. **Conclusion:** - Based on the examples and explanations, we conclude that changes around us primarily involve interaction between materials. Therefore, the correct answer to the question "Changes involve" is "interaction." **Final Answer:** Changes involve interaction. ---
