The individual temperature of the particles increased.
The individual temperature of the particles increased.

The kinetic energy of the particles decreased.
The kinetic energy of the particles decreased.

The average speed of the particles increased.
The average speed of the particles increased.

The potential energy of the particles decreased.

GPT-4o mini · Answer

The correct response is: **The average speed of the particles increased.** As the blacksmith strikes the metal, the energy from the hammer impacts the metal, causing the particles to move faster. This increase in average speed leads to an increase in temperature, making the metal glow and become more malleable.
