用量筒测质量,用弹簧测力计测体积,听起来是错误的,但是我们在解答测量物质密度的设计性实验题时,往往要巧用量筒测出物体的质量或者用弹簧测力计测出物体的体积。这样的设计题,考查对所学知识的迁移能力,在各类试题中经常出现。1用量筒测量物体的质量有的设计性试题,所给的器 Measuring the mass with a measuring cylinder and measuring the volume with a spring dynamometer sounds wrong, but when answering design questions for measuring the density of a substance, it is often necessary to use a cylinder to measure the mass of the object or measure it with a spring dynamometer. The volume of the object. This kind of design question examines the ability to transfer knowledge and often appears in various questions. 1 The measuring cylinder measures the quality of objects. Some design questions are given.
