自从学了“物态变化”这一章节后,我明白了物质的三种状态之间的关系。为了不拘泥于课本上的知识,为了探究物质“三态”之间的区别,我从多个角度进行了实验。首先,我用冰和蜡烛作为实验对象,将同等质量的冰和蜡烛放入烧杯内加热,等到冰和蜡烛熔化后,我发现融化的蜡烛比固体蜡烛体积大,而水比冰体积小,但是质量不变。可见不同状态的同种物体的体积不一样,密度也不一样。这同时让我解开了一个想了很久的问题:为什么冰块会浮在水面上呢?由于冰的 Since I learned the chapter “Change of State,” I have come to understand the relationship between the three states of matter. In order not to stick to the textbook knowledge, in order to explore the difference between matter and “trilism,” I conducted experiments from many angles. First of all, I used ice and candles as subjects. Immeasured the same mass of ice and candles in a beaker. After the ice and candles melted, I found that the melted candles were larger than solid candles and had a smaller volume than ice, but The same quality. Visible different state of the same kind of objects are not the same size, density is not the same. This at the same time let me unlock a long time thought: why ice floats on the surface? Because of the ice
