A blacksmith strikes a piece of metal with a hammer repeatedly. The metal slowly begins to glow as the temperature increases, and the metal becomes more malleable. Which changes on a microscopic level led to the visible changes in the properties of the metal? (1 point) Responses The kinetic energy of the particles decreased. The kinetic energy of the particles decreased. The potential energy of the particles decreased. The potential energy of the particles decreased. The average speed of the particles increased. The average speed of the particles increased. The individual temperature of the particles increased.
1 answer
The correct response is: The average speed of the particles increased.
As the blacksmith strikes the metal and applies energy through the hammer, the kinetic energy of the particles in the metal increases, resulting in an increase in their average speed. This increased kinetic energy raises the temperature, causing the metal to glow and become more malleable.
