It does not emit it. It takes almost 16 times the energy to change 0C ice into 0C water as it does to raise -10C ice to 0C ice. The amount of energy required to raise the same sample from 0C to 100C is only 1.25X as great as the energy to raise 0C ice to 0C water.<br /><br />Shifting the PHASE of a substance -- changing its state, such as solid to liquid, or liquid to gas -- is nearly always a change that absorbs heat, it doesn't release it. When you melt water from 0C ice to 0C water, it take 8350 joules per 25 GRAMS of ice. The water is not "warm" at that point, it is still at 0 degrees C, it has just changed state. To "warm" the water you need to continue adding energy to raise the temp from zero.<br /><br />For a 25g sample, to raise the temp from 0C to 100C -- the point at which it can boil -- requires 10,450 joules of energy. But that isn't to MAKE it boil, because boiling is another phase change, to steam. To take 100C water to 100C steam is another 56,425 joules of heat, roughly 5 times the amount needed to bring it from the freezing point to the boiling point.<br /><br />Want to see the math?

That "bubble of heat" is pushing the jet stream south, temporarily causing colder winters. Once the "bubble of heat" gets large enough it will push the jet stream so far south that it will cook us all.MDC708https://www.blogger.com/profile/02612128967177446099noreply@blogger.com
