In this video, we explore how water changes form depending on temperature. Through real-life demonstrations and simple explanations, you’ll see how liquid water becomes ice, how ice melts, and how water transforms into steam. We’ll also look at what’s happening at the particle level to understand why these changes occur. This video is a great introduction to the three states of matter—especially as seen in water—and how heat plays a key role in these transformations. Perfect for learners curious about the science in everyday life!
