用天平量筒测密度的方法常用,然而若只有天平或只有量筒,要测密度,怎么办呢?我们来看下面几例. 1.利用天平、烧杯、水、细线,怎样测出一石块的密度? 分析可用天平测出石块的质量,因为没有量筒没办法直接测出石块的体积,所以就需要利用天平、烧杯、水等想办法测出与石块体积相等的那部分水的质量,然后利用水的密度求出水 Measuring the density with the balance cylinder is commonly used, but if only the balance or only the measuring cylinder, to measure the density, how to do it? Let’s look at the following examples. 1. Using balance, beaker, water, thin line, how to measure a stone The density of the analysis can be used to determine the quality of the stone, because there is no way to directly measure the volume of the stone without a measuring cylinder, so you need to use a balance, beaker, water, etc. to find out the part of the water that is equal to the volume of the stone. Quality, then use water density to find the water
