2001年安徽省中考物理试题第28题是一道科学探究题,内容如下:如图1所示,将试管口朝下放在酒精灯火焰上方加热3~5s后,立刻竖直插入盛水的容器中某深度处不动.(1)你猜想可能产生的现象是.(2)你猜想的依据是.本题的参考答案是:(1)水会沿着试管上升.(2)酒精灯加热时,从试管中排出一部分空气,插入水槽后,外界大气压强大于试管里的气压,水会在大气压强的作用下进入试管. In 2001 Anhui Province in the physical exam question 28 is a scientific inquiry questions, as follows: As shown in Figure 1, the test tube mouth down on the top of the alcohol lamp heat 3 ~ 5s, immediately vertical into the water container (2) the basis of your guess is that the reference answer to this question is: (1) the water will rise along the test tube (2) When the alcohol lamp is heated, Excreted from the test tube part of the air into the sink, the outside atmospheric pressure is greater than the pressure in the test tube, the water will be under the action of atmospheric pressure into the test tube.
