现用初高中物理教材中都有“气体被压缩时热能增加”这个实验。该实验的做法是:迅速将活塞压下,气体的温度升高,使装于容器底部的乙醚达到燃点而燃烧。往往由于压缩时温度难以达到乙醚的燃点,实验很难成功.我用日光灯启动器改制了一个感温元 Current high school physics textbooks have “gas is compressed heat increase” experiment. The experimental approach is: the rapid reduction of the piston, the gas temperature increases, so that the bottom of the container installed in the ether to burn and burn. Often due to the compression temperature is difficult to reach the flash point of ether, the experiment is very difficult to succeed.I use a fluorescent lamp starter to transform a temperature element
