Question

A system contains bonds between particles. Which choice describes the microscopic structures of the energy in this system? There must be kinetic energy in the bonds due their particles position. There must be potential energy in the bonds due to their particles motion. There must be elastic energy in the bonds due to their particles motion. There must be potential energy in the bonds due to its particles position.

Answer 1

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).
