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

Metal is melted at 1,300°C.
Metal is melted at 1,300°C.

Metal is cooled at 1,300°C.

Answer 1

The kinetic energy of particles would be increasing in the case where the metal is heated from room temperature to 200°C. Heating increases the kinetic energy of the particles as they gain energy and move more vigorously.
