| Abstract: | 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. |
