how is energy related to the change of state represented by the model?

The energy that is related to change of state represented by given model is as follows:

$\boxed{{\text{Atoms gain energy a a liquid changes to a gas}}}$

Further Explanation:

Matter is anything that has mass and acquires space. It is composed of atoms that are bonded to each other either by weak forces or by strong forces.

States of matter:

Solid:

This state of matter has both definite volume and shape. These are generally very hard. The constituent particles in solid have regular and ordered arrangement. Intermolecular forces between these particles are the strongest while motion of particles is negligible.

Liquid:

This state of matter has definite volume but not definite shape. It can take up shape of the container in which it is kept. Intermolecular forces between liquid particles are weaker than solids but stronger than gases.

Gas:

This state of matter neither has definite shape nor definite volume. There are negligible intermolecular forces between these particles and hence their movement is maximum.

The left beaker indicates liquid molecules as these are not present in any particular ordered arrangement. These particles are not in motion as is evident from their presence only at the bottom of the beaker so their kinetic energy is zero.

The right beaker refers to gas molecules as these are far apart from each other and are in random motion with each other. This results in some kinetic energy of molecules.

Therefore atoms gain energy as liquid changes to gas.
