Question

how is energy related to the change of state represented by the model? atoms gain energy as a solid changes to a gas atoms gain energy as a liquid changes to a gas atoms lose energy as a solid changes to a gas atoms lose energy as a liquid changes to a gas

Explanation:

When a substance changes from a solid to a gas (sublimation) or from a liquid to a gas (vaporization), atoms gain energy. In the model, the change from a more - ordered state (left - side, likely solid) to a more disordered state (right - side, likely gas) indicates an increase in energy. The energy is used to break the intermolecular forces holding the atoms together in the solid or liquid state.

Answer:

Atoms gain energy as a solid changes to a gas
