What is considered a solid?
A solid is a sample of matter that retains its shape and density when not confined. Examples of solids are common table salt, table sugar, water ice, frozen carbon dioxide (dry ice), glass, rock, most metals, and wood. When a solid is heated, the atoms or molecules gain kinetic energy .
What makes a solid solid?
Something is usually described as a solid if it can hold its own shape and is hard to compress (squash). The particles in most solids are closely packed together. Even though the particles are locked into place and cannot move or slide past each other, they still vibrate a tiny bit.

What is the hardest type of solid?
Network atomic solids have a wide number of varying properties. They are usually hard, owing to the strong bonds between neighboring atoms?for example, diamonds are (currently) the hardest known material. They also tend to have high melting and boiling points due to the very strong covalent bonds.
