测固体密度是实验设计题中一个很常见的题型,其方法多种多样,主要可归纳为以下几类:1测密度大于水且不溶于水的物体密度。方法一器材:天平、量筒、水。步骤:①用天平测出物体质量m,②在量筒中倒入适量的水,记下水面所对刻度V1,③将物体浸没在水中,记下水面所对刻度V2。表达式:ρ=m/(V2-V1)方法二器材:弹簧测力计、烧杯、水、细线
Measuring solid density is a very common question in experimental design problems. Its methods are various and can be mainly classified into the following categories: 1 Density of objects with higher density than water and insoluble in water. Method one equipment: balance, graduated cylinder, water. Procedure: 1 Measure the mass of the object with the balance m, 2 Pour the appropriate amount of water into the graduated cylinder, record the scale V1, 3 on the surface of the water and immerse the object in water. Record the scale V2 on the surface of the water. Expression: ρ=m/(V2-V1) Method Two Equipment: Spring Dynamometer, Beaker, Water, Thin Line
