质量守恒定律是科学中的一条基本定律,也被称作物质守恒定律。意思是,在一个与外界隔绝的封闭系统中,质量(也包括能量)是永远不变的。这条定律隐含着物质既不能产生也不能消灭,它是自然界普遍存在的基本定律之一,广泛应用于许多领域。在化学反应中,参加反应前各物质的质量总和等于反应后生成各物质的质量总和。在任何与周围隔绝的体系中,不论发生何种
The law of conservation of mass is a fundamental law in science, also known as the law of conservation of matter. This means that in a closed system isolated from the outside world, quality (including energy) is never changed. This law implies that matter can neither be produced nor eliminated. It is one of the basic laws universally found in nature and is widely used in many fields. In a chemical reaction, the total mass of each substance before participating in the reaction is equal to the sum of the masses of the substances produced after the reaction. In any isolated system, no matter what happens
