GPT-4o mini · Answer

The correct response is: **The average speed of the particles increased.** As the blacksmith strikes the metal, energy is transferred to the atoms in the metal, causing them to move more rapidly. This increase in kinetic energy results in a rise in temperature, making the metal more malleable and causing it to glow as it gets hot.
