[实验一]用天平测物体质量.所给天平故意去掉一只调节横梁平衡的螺母.要求测量误差小于±10%.[实验二]测量物体的密度.待测物体的密度小于水的密度,而且形状不规则.[实验三]测液体的比热.所用量热器系电量热器.
[Experiment 1] Use a balance to measure the mass of the object. The given balance deliberately removes a nut that adjusts beam balance. The required measurement error is less than ±10%. [Experiment 2] Density of the measured object. The density of the object to be measured is less than the density of water. And the shape is irregular. [Experiment 3] to measure the specific heat of the liquid.
