no,wait, the real prodigy is here. i'm going to type english so listen up .
.....at 25 degrees below SATP (298 K) ,gaseous dihydrogen oxide changed its enthapy content and becomes more stable as water in liquid form, it releases heat thru an exothermic reaction (similar to it gets warmer when it's snowing). where did the heat come from...the kinetic engery of the water molecules reduces therefore a slower collision frequence and less kinetic energy between these polar particles. this means electrons cannot "jump down" from a higher electron orbital to a lower one to form the regular nearly transparent emission spectrum. and the specific emission spectrum of dihydrogen oxide "gives out" the white light you "see" with your eyes....again frequency ---> wavelength (colour you see)....at least this is what i think
