上期说道,在做冰的熔化实验时,在固液共存态,应为冰的熔化过程,可是温度计的示数却上升了,这是为什么呢?小明于是和别的小组进行了交流,结果发现,在别的小组实验中,冰熔化的过程中温度计示数都有所上升,而不是像书上说的是固定不变的。小组成员一起展开了激烈的讨论,从自己的实验设计及实验过程入手查找原因。大家了解到冰熔化的温度比较低,而酒精灯的加热温度为400℃~600℃。是不是酒精灯的火焰温度高影响了周围空气的温
The last issue said that during the ice melting experiment, solid-liquid coexistence, should be the melting process of ice, but the thermometer showed an increase in the number, which is why? Xiao Ming then and other groups were exchanged, and found that In other panel experiments, thermometer readings increased during the ice melting process, not as the book said. Team members started a heated discussion, starting from their own experimental design and experimental process to find out why. We all know that the melting temperature of ice is relatively low, while the heating temperature of the alcohol lamp is 400 ℃ ~ 600 ℃. Is not the high flame temperature of alcohol lamp affects the temperature of the surrounding air
