化学变化中质量不守恒

Mass in a chemical change is not constant

根据相对论中的质能关系E=mc2,如果一个物体以辐射形式放出能量,那么它的质量就要减少,由于在化学变化中将伴随着能量的释放和吸收,经典化学中的质量守恒定律和相对论中的质能关系是相矛盾的;质能关系的存在表明在化学变化中质量不是守恒的,实际上是质能的守恒.

According to the relation between mass and energy in the Relation Theory, E=mc^2, mass of an object will decrease if it releases energy by radiation. Because of the release and absorption of energy in a chemical change, Conservation of Mass in a classic chemistry is conflicted with the relation between mass and energy in the Relation Theory, which indicates that mass in a chemical change is not constant. In fact, mass and energy as a whole is constant.
