Study Hints at How Hot Water Can Freeze Faster Than Cold
In physics, chilling out isn't as simple as it seems.A hot object can cool more quickly than a warm one, a new study finds. When chilled, a warmer system cooled off in less time than it took a cooler system to reach the same low temperature. And in some cases, the speedup was even exponential, physicists report in the Aug. 6 Nature.
