在“观察水的沸腾”的实验中
⑴实验中如果将将温度计的玻璃泡碰到杯底,这样会使得测得的温度值_________(偏小/偏大),观察温度计示数时视线A、B、C如图所示,其中正确的是_________.
⑵点燃酒精灯后即开始计时,当水中有气泡上升时,每隔1min记录的水的温度如下表所示.
时间/min | … | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 |
温度/℃ | … | 92 | 94 | 96 | 97 | 98 | 98 | 98 | 98 |
②利用表中数据,在乙图中描绘出水的温度随时间变化的关系图线;
③由实验数据分析可知:水的沸点是_________℃,水在沸腾过程中,需要_________(吸收/放出)热量,温度_________(升高/不变/降低).
⑶实验结束后,同学们相互交流时,发现各自测出的水的沸点大都不是100℃,可能原因是_________(写出一点);有人觉得得把水加热到沸腾的时间过长,为了节约课堂时间,请你提出一条合理化建议:___________________________.
