Description

一种气压与沸点关系的演示装置
技术领域
本发明涉及水沸点温度的测量及其与气压之间关系演示,主要用于教育教学目的,具体地说是一种气压与沸点关系的演示装置。
背景技术
气压越低,水的沸点越低,是物理学的常识性理论,如何简单有效、直观的在课堂上展示出来,使学生容易理解并不容易。
发明内容
为更好、更直接的反映出气压与沸点之间的变化关系,本发明提供了一种气压与沸点关系的演示装置。
本发明是这样实现的:支杆垂直的安装在底座上,支杆上安装载物台,底座上放置酒精灯,载物台上放置加热瓶,加热瓶中部瓶壁上设置温度计,瓶塞上安装气管,气管上有截止阀。
所述的加热瓶为透明的。
本发明的有益效果是:结构简单,可借助通用物理实验设备组合完成,演示效果形象、直观。
附图说明
下面结合附图作进一步说明。
图1是本发明的结构示意图。
图中1、气管,2、截止阀,3、瓶塞,4、加热瓶,5、载物台,6、支杆,7、酒精灯,8、底座,9、温度计。
具体实施方式
如图所示,支杆6垂直的安装在底座8上,支杆6上安装载物台5,底座8上放置酒精灯7,载物台5上放置加热瓶4,加热瓶4中部瓶壁上设置温度计9,瓶塞3上安装气管1,气管1上有截止阀2。
使用时,将设备按图1放置完成,加热瓶4内注水,以淹没温度计2-3厘米为宜,盖好瓶塞3,将气管1与抽气机或压缩机连接,并读取抽气机或压缩机的气压值,记录,用酒精灯7给加热瓶4加热,通过温度计9观察水沸腾时的温度,并记录,反复改变加热瓶4内的气压值,计算或对比不同气压值下沸点温度,即可得到气压与沸点关系的直观演示。
