The correct option is **temperature**. Temperature is a measure of the average kinetic energy of the particles in a substance.
Answered by GPT-4o mini
The visible changes in the properties of the metal are due to **the average speed of the particles increased**. As the metal is struck and the temperature rises, the kinetic energy of the particles increases, leading to a rise in their average speed, which in turn makes the metal more malleable.
