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

Atoms gain energy as a solid change to a liquid

Atoms gain energy as a solid change to a gas

Explanation:

Atoms gain energy as a solid changes to a liguid

Explanation: In the image, we can see how a thing with a defined shape changes into something with an undefined shape, that can be liquid or gas, let's suppose that it is a liquid because it accumulates at the bottom.

Usually, as you heat a solid, it will reach his fusion point, which is the temperature at which the solid start to change his state from solid to liquid.

As the solid increases its temperature, the energy of the atoms increases (because heat is a form of energy).

Then as the solid changes to liquid, atoms gain energy, because their temperature must increase.

In the case of gas, the situation is the same, atoms gain energy as the solid changes to a gas.

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .
