测量物质密度的实验是初中阶段非常重要的实验,通过不同的器材可以设计不同的测量物质密度的方法,但有些测量方法可能会导致所测物质的密度偏大或偏小.一、导致被测物质的密度值偏大物质密度的测量值偏大,主要原因有两个:在测量过程中,所测物体的质量偏大或体积偏小.1.在测量固体的质量时,如果将固体沾水后再进行测量,会导致所测固体的质量偏 The experiment of measuring the density of matter is a very important experiment in junior middle school. Different methods of measuring the density of matter can be designed by different equipment, but some methods may result in the density of the measured matter being too large or too small. Material density value is too large The measurement value of material density is too large, there are two main reasons: in the measurement process, the mass of the measured object is too large or small size .1 in the measurement of solid quality, if the solid dip After water measurement, will lead to the quality of the measured partial bias
