You need to reread the wiki, dimwit. It does not make sense prima facia.
Water acts almost like a perfect black body and behaves differently than most every other molecule. Reflective white things typically have a low emissivity.
If you knew what you were talking about you would talk about specific heat. You said 'it loses energy fast, and doesn't heat readily,' which is wrong but that is to be expected from you. You know nothing more about chemistry than you do physics.
You do not even have the ability to quickly process what you read on wikipedia.
