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.
【小题1】Hundreds of years ago, Sir Francis Bacon found _______.

Warm water freezes more quickly than cold water. Sir Francis Bacon said that almost four hundred years ago. But few people believed him. Later, a Canadian scientist George Kell proved the English scholar was right. Dr.Kell filled an open jar（罐子）with cold water. He filled another with warm water. He put them both in the same low temperature. And the warm water froze first.

  What was the reason? Some of the warm water changed into vapour. It went into the air. This meant that less of the warm water was left to freeze. And so the warm water froze faster than the cold water.

A. there was less of it left        B. there was more of it left

C. something else was added to it  D. its jar was much bigger
