The ​ (a)   , solid, liquid, and gas, are defined by the behavior and arrangement of atoms and ​ (b)   . In solids, particles ​ (c)   within a fixed position, giving a definite shape and volume. Gases have more ​ (d)   energy, allowing molecules to slide past each other, changing shape while keeping the same volume. Gases, with the ​ (e)   kinetic energy, have freely moving particles that fill any space available, lacking fixed shape and volume.
