针对沸点与气压关系的传统实验装置只能靠推理得出实验结论的缺点,在传统实验装置的基础上先插入电子温度计,发现该装置能使28℃的水沸腾,激发学生的好奇心和探索热情;在插入电子温度计的实验装置的基础上再接入真空表,可直观显示沸点与气压的关系。在教学中可根据不同的教学目的,选择合适的装置,达到理想的实验效果。 According to the traditional boiling point and atmospheric pressure experimental conclusion can only draw the conclusions of the experimental reasoning shortcomings in the traditional experimental device based on the first electronic thermometer inserted and found that the device can boil the water at 28 ℃ to stimulate curiosity and explore students Enthusiasm; inserted in the electronic thermometer experimental device based on the access to the vacuum gauge, you can visually display the relationship between boiling point and pressure. In teaching, according to different teaching purposes, choose the appropriate device to achieve the desired experimental results.
