Metal is at room temperature, 37°C.
Metal is at room temperature, 37°C.

Metal is heated from room temperature to 200°C.
Metal is heated from room temperature to 200°C.

Metal is cooled at 1,300°C.

Answer 1

The kinetic energy of particles would be increasing in the case where metal is heated from room temperature to 200°C.

As the temperature of a substance increases, the kinetic energy of its particles also increases because they move faster at higher temperatures.
