Answer:
Electrical energy
Explanation:
Electrical energy is caused by the moving of electrons.
hope it helps!
I believe the change of state shown in the model is deposition.
Deposition is a process in which gases change phase and turns directly in solids without passing through the liquid phase. It is the opposite of sublimation.
One of the major difference between gases and solids is the distance between molecules; in gases the inter molecular spaces are large, while in solid they are very small, making solids be the most dense, with closely packed molecules. This is evident in the diagram, the phase changed from gases to solids.
Liquid silver is less dense than solid silver, so the solid silver would sink.

well you can't walk through the air but you can't walk through a concrete wall because all of the solid atoms holding it together
