高一物理第300页所印盖·吕萨克定律实验装置图,从道理上讲是可以的,我曾按教材所述装置进行过多次实验,结果误差都很大,分析其失败原因,可能有两个:第一、0℃时气体的体积的数值V_0很难测准;第二、用作气体容器的烧瓶,其颈部及以外的玻璃管未能浸没水中,致使容器中部分气体的温度各异。且只要烧杯中水温不等于室温,则由于吸热、散热关系,容器中各部分气体的温度永远不会相同,必将严重干扰实验。改用高一物理第362页的验证气态方程的实验装置,来验证盖·吕萨克定律效果较好。(若无气态方程实验装置,也可用沈阳
The layout of the experimental apparatus of the lid and Lusak’s law on the 300th page of Physics in Physics and Physics, is logically correct. I have conducted many experiments according to the device described in the textbook, and the results are very inaccurate. We analyze the reasons for the failure. There may be two: First, the value of the volume of gas at 0°C, V_0, is difficult to measure; second, the flask used as a gas container, the neck and other glass tubes fail to submerge the water, resulting in some gas in the container. The temperature varies. And as long as the water temperature in the beaker is not equal to room temperature, due to the relationship of heat absorption and heat dissipation, the temperature of each part of the gas in the container will never be the same, which will seriously interfere with the experiment. Use the experimental apparatus of the verification of the gaseous state equation on page 362 of the first-year physics to verify that Guy-Lussack’s law works well. (If there is no experimental device for the gaseous equation, Shenyang can also be used
