橡皮泥的密度大于水的密度,由于它具有容易发生形变的特点,所以在浮力实验中经常用到.例1如何用量筒、水、橡皮泥测定橡皮泥的密度.分析:此类实验需测浮力,如何测出浮力,为外乎两种情况;一是物体的密度大于水的密度,运用阿基米德原理,用弹簧测力计、水、细线来测;二是物体的密度小于水的密度,运用物体浮在液面上的条件.用量
Plasticine density is greater than the density of water, because it has the characteristics of easy deformation, so often used in buoyancy experiments. Example 1 How to measure the density of plasticine using a measuring cylinder, water, and plasticine. Analysis: This kind of experiment needs to measure the buoyancy, how to measure the buoyancy, is outside the two situations; First, the density of the object is greater than the density of water, using the Archimedes principle, with the spring dynamometer, water, thin line to test Second, the density of the object is less than the density of water, and the condition of the object floating on the liquid surface is used.
