We present a sequence of two physics experiments, designed for use with secondary students, which investigate the specific heat of sand, both qualitatively and quantitatively, without a calorimeter. We use two LM35 temperature sensors and an Arduino prototype board for data acquisition. The results are good and allow teachers to discuss the behaviours of water and sand in the heating and cooling processes. Our proposals are suitable for use in the teaching of high school students and lead to meaningful learning about this physical property.

使用 Arduino 板研究沙子的比热

我们展示了一系列两个物理实验,专为中学生设计,在没有热量计的情况下,定性和定量地研究沙子的比热。我们使用两个 LM35 温度传感器和一个 Arduino 原型板进行数据采集。结果很好,让教师可以讨论水和沙在加热和冷却过程中的行为。我们的建议适用于高中生的教学,并有助于对这种物理特性进行有意义的学习。
