水沸腾时,饱和汽压等于大气压是中师《物理学》教学的难点之一.实践是检验真理的标准,作一教具测试水沸腾时的饱和汽压值就解决了上述的难点.现介绍于后.1 实验装置如图所示,装置由三部分组成:(1)盛水器:雪碧瓶 下部.(2)饱和汽压测试装置:软塑胶水瓶(壁下部打孔).(3)抽水泵:一次性输液管、与它配套的控液夹、硬塑管和洗耳球(顶端有孔).装置方法:先将被粘接处清
When water boils, saturation vapor pressure is equal to atmospheric pressure is one of the difficulties in the teaching of “Physics” in the division. Practice is the standard for testing truth. As a teaching aid to test the saturation vapor pressure value when the water boils, the difficulties mentioned above are solved. After the .1 experimental device as shown in the figure, the device consists of three parts: (1) water container: lower part of the sprite bottle. (2) saturated vapor pressure test device: soft plastic water bottle (hole under the wall). (3) Suction pump: disposable infusion tube, its associated liquid-control clamp, hard plastic tube and ear wash ball (with holes at the top). Device method: first clear the bond site
