Boiling point and pressure intensity experimental teaching aid for high school physics teaching

Abstract

The invention provides a teaching aid for high school physics teaching boiling point and pressure experiment; it includes a fixed rod and a base; there are four fixed rods, and their lower ends are installed on the upper surface of the base; a No. 1 fixed block is arranged outside the upper end of the fixed rod; The No. 1 fixed block and the No. 1 fixed plate are welded together; the No. 1 fixed plate is provided with a fixed groove; the fixed groove is fixed with a pressure gauge, a thermometer and an air guide tube; the thermometer is fixed on the In the flask; the flask is installed on the surface of the asbestos mesh; the asbestos mesh is embedded in the middle of the No. 2 fixing plate; the No. 2 fixing plate and the No. 2 connecting block are welded as one; the No. 2 connecting block is internally equipped with a fixed shaft; A rotating plate is installed on the fixed shaft through a bearing; an alcohol lamp fixing seat is arranged directly below the rotating plate; the present invention is simple in structure and easy to use. Universality of the device.

Description

technical field [0001] The invention relates to the field of teaching aids, in particular to a teaching aid for boiling point and pressure experiments in high school physics teaching. Background technique [0002] When students learn book knowledge, they are assisted by teaching aids and experimental devices, which are of great help to deepen the understanding and mastery of the knowledge they have learned, especially for students who are new to learning about the relationship between boiling point and pressure. In-class experimental equipment is very necessary. In the existing teaching, there is a lack of such in-class experimental devices. The teacher either completely relies on book knowledge for teaching, or makes some non-standard self-made teaching aids to help students understand the relationship between boiling point and pressure. Reliability, as well as practical teaching purposes, fell short of the ideal. Contents of the invention [0003] The object of the pre...
