密度实验一直是中考命题的重点、热点,河北省几乎年年出实验题.为此我对该实验进行了一下归纳总结.常规类该类实验比较简单借助ρ=mV可以轻松搞定.1用天平和量筒如何测固体的密度?请写出实验步骤和表达式步骤:(1)用天平称出固体的质量m;
Density experiment has always been the focus and hot spot of the examination topic. Hebei Province produces experimental questions almost every year. For this reason, I have summarized and summarized this experiment. Conventional experiments of this type are relatively simple with ρ=mV. How do you measure the density of a solid with a graduated cylinder? Write out experimental steps and expression steps: (1) Use a balance to weigh the solid mass m;
