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 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 potential energy of the particles decreased.
The potential energy of the particles decreased.
The average speed of the particles increased.
Responses
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 potential energy of the particles decreased.
The potential energy of the particles decreased.
The average speed of the particles increased.
The correct option is The average speed of the particles increased. As the blacksmith strikes the metal, the kinetic energy of the particles increases, leading to an increase in their average speed, which raises the temperature and makes the metal more malleable.

Responses
the measurement of energy in an object due to position, conduction, or chemical composition
the measurement of energy in an object due to position, conduction, or chemical composition
a material that is a conductor of heat
a material that is a conductor of heat
the total kinetic energy of all particles in a substance
the total kinetic energy of all particles in a substance
the distance between particles and their freedom to move around
The correct option is the total kinetic energy of all particles in a substance. Thermal energy refers to the total energy of the particles in a given substance, which is related to their motion (kinetic energy).
