The greatest heat transfer occurs during the phase change from steam to water at 100°C. This phase change is known as condensation, and it involves the release of a significant amount of heat energy. When steam condenses into water, the steam molecules lose their latent heat of vaporization and convert into liquid water molecules. This latent heat of vaporization is a large amount of energy that was absorbed during the vaporization process. In contrast, options 2, 3, 4, and 5 involve temperature changes without phase changes. While there is heat transfer occurring in these cases, it is not as substantial as the heat transfer associated with a phase change. So, option 1) One gram of steam at 100°C changing to water at 100°C involves the greatest heat transfer among the given choices. |
