利用DISLab传感器探究水的沸点与大气压强的关系

摘要

针对“密闭气体压强与温度间的关系”实验的不足，将DISLab 应用到实验中，通过 DISLab 的压强传感器和温度传感器可以直接精确地读出密闭气体的压强和温度，直观地显示出“压强减少、水的沸点降低”及“压强升高、水的沸点升高”的规律。%Aiming at the deficiency of the experiment of the relation between pressure and temper-ature of sealed gas,a method using DISLab was put forward.By using pressure sensor and tempera-ture sensor,the pressure and temperature could be read directly.It was showed that the lower the pressure,the lower the boiling point of water and the higher the pressure,the higher the boiling point of water.
