分析气体定律的图象,可以加深对气体状态和变化过程的理解,从而开阔思路,提高分析问题的能力。本文试就气体定律的图象问题作些初探。一、玻意耳—马略特定律与 p-V 图象玻意耳—马略特定律的数学表达式为pV=常量。在 p-V 图象上,等温过程表示为双曲线。(1)在图1中,给出了不同温度时,等温变化过程的一组等温线①、②、③。 Analyzing the image of gas laws can deepen the understanding of the state of gases and the process of change, thus broadening ideas and improving the ability to analyze problems. This article tries to do some research on the image problem of gas law. 1. The Boyle-Marlow Law and the mathematical expression of the p-V image Boyle-Malo law are pV=constant. On p-V images, the isothermal process is hyperbolic. (1) In Fig. 1, a set of isotherms 1, 2 and 3 for the isothermal change process at different temperatures are given.
