Problems solved by technology

[0009] The knowledge points involved in the above, when the teacher is teaching, most of the time a single introduction and explanation, resulting in artificial segmentation, and there is no corresponding demonstration tool to combine the above knowledge points more or less and intuitively display Students can only understand it single-handedly, which will restrict the teaching effect. Therefore, we should design a batch of interesting demonstration tools based on comprehensive demonstration teaching.

Abstract

The invention relates to the technical field of a teaching aid for comprehensive teaching of physical chemistry, and concretely relates to an interesting demonstration appliance for comprehensive teaching of physical chemistry. An alcohol lamp is used as a heating source to cause thermal expansion and contraction of the gas in a gas cylinder, and through specially designed transmission, the work of a stirring rod, the up and down movement of a beaker, the lighting or the extinction of an indicator light are finally realized. The interesting demonstration appliance organically combines thermalexpansion and contraction, transmission and circuit in physical chemistry, and provides the interesting demonstration appliance for physical and chemical synthesis, which greatly enhances a teaching display function of the teaching aid and improves the teaching effect.

Description

technical field [0001] The invention relates to the technical field of comprehensive physical and chemical demonstration tools, in particular to an interesting demonstration tool for comprehensive physical and chemical teaching. Background technique [0002] Physics is a subject that studies the most general laws of motion of matter and the basic structure of matter. As the leading discipline of natural science, physics studies the most basic forms and laws of motion of all matter, ranging from the universe to elementary particles, and thus becomes the research basis of other natural science disciplines. Its theoretical structure fully uses mathematics as its working language, and experiments are the sole criterion for testing the correctness of the theory. It is the most sophisticated natural science discipline today. [0003] Chemistry is a kind of natural science, which studies the composition, properties, structure and changes of substances at the molecular and atomic l...
