The individual temperature of the particles increased.

GPT-4o mini · Answer

The correct response is: **The average speed of the particles increased.** As the blacksmith strikes the metal, the kinetic energy of the particles increases due to the heat generated from the repeated hammering. This increase in kinetic energy results in an increase in the average speed of the particles, causing the metal to heat up and become more malleable.
