实验目的:
1.观察水沸腾时的温度。 2. 观察水沸腾过程中的现象。
器材:烧杯(beaker),水,温度计(thermometer),酒精灯(ethanol light),火柴。
步骤:
1.在烧杯里盛100g左右的水。
2. 在水中放入温度计。
3. 加热杯中的水,并观察温度计的示数和水的情况。
结果:当温度达到一百摄氏度时,水面出现大量气泡。
结论:
1. 水在一百摄氏度时开始沸腾。
2. 水在沸腾过程中有大量气泡产生。
Aim: To find out: 1.the temperature when water is boiling; 2. what happens when water is boiling.
Apparatus: beaker; water; thermometer; ethanol light; beaker holder; match.
Method:
1. Fill about 100g water in the beaker.
2. Put a thermometer in the water.
3. Heat the water in the beaker, and watch the readings of the thermometer.
Result: Bubbles begin to appear when the temperature reaches 100 Centigrade.
Conclusion:
1. The water boils when the temperature reaches 100 Centigrade.
2. A lot of bubbles appear during the boiling.
