You must be surprised. The answer is that hot water freezes into ice first. When I read this introduction in a book, I felt the same way as you, so I started the experiment with my mother with great interest. I poured the same amount of hot water and cold water into two glasses, marked them, put them in the refrigerator and waited patiently. Ten minutes later, I opened the refrigerator and found a thin layer of fog on the inner wall of the cold water cup, and the inner wall of the hot water cup was covered with small drops of water. Home.sanwen8.cn felt the hot water, and the water became warmer; Touch the cold water again. The water is cold. Ten minutes later, when I looked again, the hot water turned into cold water, but the cold water was vaguely frozen, like cracked glass. I looked at my mother doubtfully and said, "It's not cold water that freezes first, is it?" When cold water is covered with a thin layer of ice, hot water remains unchanged. Even if the cold water is covered with a thick layer of ice, the hot water is still indifferent. At this time, my mother and I were convinced that cold water would freeze first. My mother took the opportunity to educate me: "Many things can only be concluded if you try them yourself, and sometimes even mistakes will appear in books." I'm angry, too. I wonder how many people have been cheated by that book. After writing for over an hour, I walked into the kitchen with the last glimmer of hope. When I opened the refrigerator door, I was shocked and a miracle appeared. The cup of hot water turned into solid ice, and the cup of "preemptive" cold water gurgled under the thick ice. My mother and I stood in front of the refrigerator dumbfounded, and could hardly believe the facts in front of us. My mother took a deep breath and said to me earnestly, "that's the way it is." No one can predict the result until the last moment. " Although I don't know why hot water freezes into ice first, this experiment has benefited me more than the experiment itself. I understand that no matter what happened before, the result is hard to say, and it is not easy to draw conclusions from the problem. While I was thinking about this article, there was a table tennis match on TV. If China's Wang scored another goal, he might win the game. Mother said, "Just like playing table tennis, only after playing the last ball can Wang win.
