Why are sparks produced when a pair of scissors is sharpened against a grinding wheel?
Sparks are produced when a pair of scissors is sharpened against a grinding wheel due to the friction generated between the metal of the scissors and the abrasive surface of the grinding wheel. This friction generates heat, causing small particles of metal to oxidize and ignite, creating visible sparks. Additionally, the high speed at which the grinding wheel rotates contributes to the intensity of the sparks as metal shavings are ejected. The process is a combination of mechanical action and thermal energy release.
