在“观察水的沸腾”实验中：
（1）如图ABC所示，是小明同学用温度计测小烧杯中水的初温时的操作图．
A是操作过程，B是读数过程，C是读取的温度．
①A图中操作的错误是
②B图中读数的错误是
③若操作正确无误，根据C图可知此时烧杯中水的实际初始温度是
（2）小明同学在利用如图D所示的装置做实验时，发现从开始给水加热到水开始沸腾所用的时间过长，请你帮助他找出可能存在的原因．（写出两种）
①
②
（3）在观察水的沸腾过程中，观察到沸腾前和沸腾时水中气泡上升过程中的两种情况，如图E所示，则图
（4）从点燃酒精灯加热开始计时，当液体中有气泡上升时，每隔1min记录水的温度如表：
①从上表数据中可以看出；水的沸点是
②在图G中以时间为横轴，以温度为纵轴，以表格中的数据作出水的沸腾图象．
水沸腾后如果停止对水加热，水
（5）小明突然想到这样一个问题：在水沸腾前，温度计示数上升速度是否是均匀的呢？根据实验数据，作出了如图F所示的温度随时间变化的图象，温度计示数上升速度先慢后快再慢；试解释造成这种现象的原因：

（1）如图ABC所示，是小明同学用温度计测小烧杯中水的初温时的操作图．
A是操作过程，B是读数过程，C是读取的温度．
①A图中操作的错误是
温度计的玻璃泡碰到了容器底
温度计的玻璃泡碰到了容器底
；②B图中读数的错误是
读数时，温度计玻璃泡离开了被测液体
读数时，温度计玻璃泡离开了被测液体
；③若操作正确无误，根据C图可知此时烧杯中水的实际初始温度是
48
48
℃．（2）小明同学在利用如图D所示的装置做实验时，发现从开始给水加热到水开始沸腾所用的时间过长，请你帮助他找出可能存在的原因．（写出两种）
①
水的质量太大
水的质量太大
；解决办法是：适当减少水量
适当减少水量
．②
水的初温太低
水的初温太低
．解决办法是：适当提高水的初温
适当提高水的初温
．（3）在观察水的沸腾过程中，观察到沸腾前和沸腾时水中气泡上升过程中的两种情况，如图E所示，则图
乙
乙
是水在沸腾前的情况，图甲
甲
则是水沸腾时的图象．（4）从点燃酒精灯加热开始计时，当液体中有气泡上升时，每隔1min记录水的温度如表：
| 时间/min | … | 11 | 12 | 13 | 14 | 15 | 16 | 17 | 18 | 19 | 20 |
| 温度/℃ | … | 80 | 84 | 88 | 92 | 96 | 98 | 98 | 98 | 98 | 98 |
98
98
℃；②在图G中以时间为横轴，以温度为纵轴，以表格中的数据作出水的沸腾图象．
水沸腾后如果停止对水加热，水
不能
不能
（选填“能”、“不能”）继续沸腾，结合上面的实验现象可知水沸腾的条件是达到沸点
达到沸点
，继续吸热
继续吸热
．（5）小明突然想到这样一个问题：在水沸腾前，温度计示数上升速度是否是均匀的呢？根据实验数据，作出了如图F所示的温度随时间变化的图象，温度计示数上升速度先慢后快再慢；试解释造成这种现象的原因：
开始石棉网和烧杯，首先吸热升温，所以水温上升较慢
开始石棉网和烧杯，首先吸热升温，所以水温上升较慢
，当石棉网与烧杯温度到达一定高度后，水吸热温度上升加快
当石棉网与烧杯温度到达一定高度后，水吸热温度上升加快
，水温较高时散热较快，同时水汽化速度加快，汽化过程需要吸热，水温上升放慢
水温较高时散热较快，同时水汽化速度加快，汽化过程需要吸热，水温上升放慢
