Answer 1

Answer:

Solid, one of the three basic states of matter, the others being liquid and gas. (Sometimes plasmas, or ionized gases, are considered a fourth state of matter.) A solid forms from liquid or gas because the energy of atoms decreases when the atoms take up a relatively ordered, three-dimensional structure.
