玻意耳定律指出,对于在固定温度下保持一定量的理想气体,其 压力 ([latex]P[/latex])和体积([latex]V[/latex])成反比。这意味着它们的乘积是一个常数([latex]k[/latex])。数学上可以表示为 [latex]P \propto \frac{1}{V}[/latex] 或 [latex]PV = k[/latex]。.

波义耳定律由罗伯特·波义耳于1662年发表,描述了在温度和气体量恒定的情况下,气体压力和体积之间的关系。波义耳使用J形玻璃管进行实验,管内空气量固定,并通过添加汞来改变压力。他观察到,随着气体压力的增加,其体积成比例地减小。这种反比关系可以用数学公式表示为[latex]P ∝ 1/V[/latex],或者更常见的是[latex]P₁V₁ = P₂V₂[/latex],适用于等温(恒温)过程中给定质量的气体。
The French physicist Edme Mariotte discovered the same law independently around 1679, which is why it is often referred to as Mariotte’s law in French-speaking countries. Boyle’s law was a crucial step in the development of the atomic theory of matter and the kinetic theory of gases. It provided the first quantitative relationship describing gas behavior, suggesting that gases are composed of tiny particles with large amounts of empty space between them. Compressing the gas reduces this empty space, thereby increasing the frequency of particle collisions with the container walls, which is perceived as an increase in pressure. It is one of the fundamental empirical laws that were later combined to form the ideal gas law.
