家用保温瓶能很好的减缓热传递,还可以演示一些有趣的物理实验. 1.演示水蒸气的液化现象在保温瓶中装入一定量的沸水(至瓶颈附近效果最佳),打开瓶塞,将铁块或玻璃斜靠在瓶口即可看到水蒸气液化形成的小水珠.
Home thermos bottle can well slow the heat transfer, but also can demonstrate some interesting physics experiments. 1. Demonstrate the liquefaction of water vapor in the thermos bottle into a certain amount of boiling water (best effect near the bottleneck), open the bottle stopper 3. Leaning the iron or glass on the bottle mouth can see the small water droplets formed by the liquefaction of water vapor.
