explain
Temperature is a measure of the average kinetic energy of the particles in a substance. Kinetic energy refers to the energy of motion, and in the case of particles, it is the energy associated with their movement. When the particles in a substance have higher average kinetic energy, the substance is considered to have a higher temperature. Temperature is typically measured using a thermometer and is expressed in units such as degrees Celsius or Fahrenheit.
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 average speed of the particles increased.
The average speed 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 correct response is:
The individual temperature of the particles increased.
The average speed of the particles increased.
