GPT-4o mini · Answer

The correct response is: **The average speed of the particles increased.** As the blacksmith strikes the metal with a hammer, the energy transferred to the metal increases the kinetic energy of the particles, causing them to move more rapidly. This increase in particle motion results in a rise in temperature, making the metal more malleable. Thus, the average speed of the particles indeed increases, leading to the visible changes in the properties of the metal.
