Dater Name Part 5: Specific Heat of Water For such a small molecule, water has a very high specific heat. This means it takes a lot of energy to raise the temperature of water. Another important property is the range of temperature for which water remains a liquid. When water evaporates, like from sweat, it also removes a lot of heat from our body. Using the data below, create a graph to demonstrate the heating curve of water. The water starts...
