A system contains bonds between particles. Which choice describes the microscopic structures of the energy in this system? There

borishaifa [10]

Answer:

The correct answer is: There must be potential energy in the bonds due to its particles position.

Explanation:

Potential energy is a kind of energy which is stored in an object due to its position or configuration. For example, if there is a ball in the fifth floor of a building, it has a determined potential energy which is converted to kinetic energy when the ball fall down. The same is in the case of the chemical bonds: the particles or atoms have potential energy related to their relative positions in the system. In fact, chemical energy is considered a form of potential energy (stored in chemical bonds).
