Hi, I'm now studying evaporation and condensation and I have a question. Why even when water boils, its temperature doesn't exceed 100 C? Where did the energy gotten from environment go? What was it used for? Examining structure of water and vapour molecules are given as a hint, but I see no correlation between that energy case and structure of molecules. Are there some rules concerning kinetic energy of a liquid? Also - I think it's related - why people feel cold after warm bath? Is it because our body gives heat to environment?
