The solid changes state and becomes a liquid because the particles are heated, therefore needing mor room.
If a solid is subjected to heat, it will expand. On reaching its melting point, the solid will become liquid. At boiling point it will convert in to gaseous form. These are the three states of a matter.
If the matter is in a liquid state, add heat to turn liquid to vapor. Remove heat to form a solid. If it is in the form of a vapor, remove heat to form a liquid, and remove more heat to form a solid. If it is in the form of a solid, add heat to turn it into a liquid. Add more heat to turn into a vapor.
To change the state of matter, you need to add or remove energy. For example, to change a solid to a liquid, heat is added to increase the temperature until it reaches the melting point. Likewise, to change a liquid to a gas, heat is added to increase the temperature until it reaches the boiling point.
To change something from a solid to a liquid, you need to add heat energy to the solid. This process is called melting. As heat is applied, the solid's particles gain enough energy to overcome the forces holding them together in a rigid structure, allowing them to move more freely and change into a liquid state.
To change one state of matter to another, you need to either add or remove heat energy. For example, to change a solid to a liquid, you would need to add heat energy to melt the solid. Similarly, to change a liquid to a gas, you would need to add heat energy to evaporate the liquid.
Add heat.
latent heat of fusion.
You add heat :)

It is called sublimation when you turn a solid into a gas. When you turn a gas into a solid it is called deposition.
You can add more of a solid reactant, you can add heat, or you can add a catalyst.
Nothing? If you do nothing to it, nothing will happen to it.
If you add heat to matter, it can either get it hotter, or it can change the state of matter (for example, from solid to liquid).
If the matter is in a liquid state, add heat to turn liquid to vapor. Remove heat to form a solid. If it is in the form of a vapor, remove heat to form a liquid, and remove more heat to form a solid. If it is in the form of a solid, add heat to turn it into a liquid. Add more heat to turn into a vapor.

Energy because energy can be used as heat.
