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. 
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 temperature of the metal rises, causing an increase in the average kinetic energy and speed of the particles. This increase in energy helps the metal become more malleable.
