氧化

氧化 refers to the chemical process in which a substance combines with oxygen, often leading to the formation of oxides. It is commonly associated with rusting or the degradation of materials when exposed to air or moisture.

The character 氧 (yǎng) means 'oxygen,' and 化 (huà) means 'to change' or 'to transform.' Together, they literally mean 'oxygen transformation,' reflecting the chemical nature of the process.

Oxidation is a fundamental concept in chemistry and is widely discussed in scientific contexts. In daily life, people might refer to oxidation when talking about food spoilage, metal corrosion, or even skin aging. Understanding oxidation helps in preserving materials and maintaining health.
