Warmwaterfreezesmorequicklythancoldwater.SirFrancisBaconsaidthatalmostfourhundredyear...
Warm water freezes more quickly than cold water. Sir Francis Bacon said that almost four hundred years ago. But few people believed him until 1970. In that year a Canadian scientist George Kill proved the English professor was right. Dr Kill filled an open oil pail(桶) with cold water. He filled another with warm water. He put both in the same low temperature. The warm water froze first. The lack of covers on the pails is the secret. Some of the warm water changed into vapor. This meant that less of the warm water was left to be frozen.And so the warm water froze faster than the cold water even though it had a greater temperature drop to make.

温水比冷水更快结冰。差不多400多年前 Francis Bacon 先生就这样说了。但是很少人相信他,直到1970年。那一年,加拿大的科学家Geoge Kell 证明了该英国物理学家的说法是对的。Kell 博士用冷水装满一个没有盖的碗。用温水装满另一个没有盖的碗。他把这两个碗放早同样低的温度下,温水先结冰了。
碗没有盖就是其中的秘密。有些温水转化成了水蒸气,扩散到空气中。这说明较少的温水留下用来结冰。所以温水比冷水更快结冰。
希望采纳!!
