Answer:
D) the motion of its particles increases
Explanation:
When heat is added to a solid substance, the particles in the solid gains kinetic energy and the motion of the particles increases.
Answer: The motion of its particles increases.
Explanation: When heat energy is applied to a solid substances its particles acquire kinetic energy. As the kinetic energy of the particles increases, the bonds between the particles begin to break, and the particles engages in a random motion. As the heat energy increases, their kinetic energy increases and consequently their is an increase in the motion of the particles.
