Temperature Phase change zone Freezing Melting 3. Water is the most commonly used natural phase change material (PCM). As shown in the figure, PCM experiences three stages when energy is provided. Which of the following is inccorrect about PCM? A. Stage (1) & (3) are sensible heating B. In stage (2), latent heat of PCM is used to change its phase instead of changing the temperature C. Once phase changes, PCM cannot adapt to temperature change in its environment D....
