Which phenomenon causes a blacksmith's quench oil to slowly degrade at elevated temperatures?

💡 Explanation

Homolytic cleavage creates free radicals in hydrocarbons, causing oxidation and polymerization of the oil because increased thermal energy promotes bond breakage. Therefore, the oil degrades due to chain reactions rather than viscosity changes alone.
