一、温度计的作用1.晶体、非晶体熔化和凝固实验(图1),利用温度计测量不同时间的温度,得出晶体、非晶体熔化和凝固的特点,也可以测出晶体的熔点和凝固点.2.水沸腾实验(图2),利用温度计测量出水沸腾前和沸腾后的温度,得出沸腾的特点,也可以测出不同液体的沸点.3.液化实验(图3),利用温度计测量出 First, the role of the thermometer 1. Crystallization, non-crystal melting and solidification experiment (Figure 1), the use of a thermometer to measure the temperature at different times, come to the crystal, amorphous melting and solidification characteristics can also be measured crystal melting point and freezing point. 2. Boiling water experiment (Figure 2), the use of a thermometer to measure the temperature before and after boiling water boiling, boiling characteristics can also be measured in different liquids boiling point .3 liquefaction experiment (Figure 3), using a thermometer to measure
