智能手机在气体摩尔体积测定实验中的应用

Application of Smart Phone in Gas Molar Volume Measurement Experiment

利用真空保鲜盒作为测定气体摩尔体积实验的实验装置,并借助智能手机的气压传感器通过手机软件Phyphox来测定实验装置内的压强变化,以此来测定标况下气体摩尔体积。实验结果表明改进后的实验取得了良好的效果,并且改进后的方法更易于学生动手操作。

The vacuum fresh-keeping box is used as an experimental device to measure the gas molar volume, and the pressure change of the experimental device is measured by the smart phone’s pressure sensor through the smart phone app Phyphox, so as to measure the gas molar volume under the normal condition. The experimental results show that the improved experiment has achieved good results, and the improved method is easier for students to operate.
