喷泉实验是高中化学第二册中重要的实验,也是高考中重要的考点之一,它往往与其它问题组合成具有探究性、综合性较强的能力考查型题目,为命题者青睐.下面谈一谈有关喷泉实验问题.一、喷泉实验形成的原理喷泉实验是一种宏观的液体喷涌现象,既有天然的,也有人为的.它的形成主要是因为容器内外存在较大的压强差.在这种压强差的作用下,液体快速流动,通过带有尖嘴的导管喷出来,即形成喷泉.二、喷泉实验形成的条件分析
Fountain experiment is an important experiment in the second volume of high school chemistry, is also one of the important entrance examination, it is often combined with other problems into a research, comprehensive ability to examine the type of topic, favored by the proponents. Talk about the fountain experiment problems.First, the principle of the formation of fountain experiment Fountain experiment is a macroscopic phenomenon of liquid spewing, both natural and man-made.The formation of the main reason is that there is a large pressure difference inside and outside the container in Under the action of this pressure difference, the liquid flows rapidly and is ejected through the pipe with sharp beaks to form a fountain.
