The other night we left a bucket of water out for = the horse and donkey. The overnight temperature dropped to about -12c. = It was a squarish plastic bucket, probably about 12 inches by 12 inches = by about 14 inches high. (I apologize for being metrically challenged = on some measurements). The water was frozen into a solid block by = morning. In all, the bucket was probably outside for 12 hours. We = brought the bucket in the house, where the temperature was about 17C. = After 48 hours of being inside, there was still ice floating in the = bucket. My question is, why does it take so much longer for the water = to thaw than to freeze. To my mind, if it took 12 hours (or less) to = freeze at -12C temperature, shouldn't it take less time to thaw at a = temperature in excess of +12C?
