A solid is a collection of tightly packed molecules that are bound together and cannot freely move around. When energy is added (heat for example) the bonds begin to break down allowing the molecules or atoms (depending on whether it's an element or compound) to move more freely, this causes the matter to change state from solid to liquid.
Take water for example, the water molecules are tightly packed when water is cooled to form ice, as it heats the bonds break down forming water. If you heat further you get steam, the molecular bonds breaking down further.
Some things even skip the liquid stage; carbon dioxide as a solid, also known as dry ice goes straight from a solid to a gas at room temperature, this is called sublimation.
gas or a liquid
The forces holding the atoms together are weaker in liquids than in solids -Apex
because some solids have extreme strong force of attraction

All the solids change the physical state (from solid to liquid or gas, crystallization structure, etc.) or the chemical state by heating.
Solids. (Anything that isn't a liquid or a gas)
freezing
gas or a liquid
Solids are rigid.
it can separate solids from a liquid or different size solids as in a screen
The change of state from a solid to a liquid is called melting.
Liquids have the form of the containers.

No,not all solid dissolves in different liquid.
because some solids have extreme strong force of attraction
Usually you freeze liquids so that they harden into solids.
a solid turns into a liquid or the liquid stage when it reaches its melting point.
