9. If something vibrates, sounds will be produced.

10. Chemical energy is emitted and converted into thermal energy (heat) and light energy when wood is burned in a fireplace.

11. The law of conservation of energy states that energy can neither be created nor destroyed - only converted from one form of energy to another.

12. Sound waves travel through vibrating objects, which vibrate other nearby objects, taking the sound with them.

13. Heat causes inter-particle bonds to weaken and break when consumed by a material, resulting in a change of state. The temperature and thus the thermal energy of the hot body would decrease.

14. The process of heat conduction entails the transfer of kinetic energy from one molecule to another. Kinetic energy, also known as motion energy, is an energy that can be applied to another entity. Metals are usually excellent heat conductors.

Correct it if wrong. Hope it helps!
