उत्तर
The particles of some forms of matter move constantly
The statement that the particles of some forms of matter move constantly is incorrect because the particles of matter of all three states– solid, liquid and gas –are moving constantly. Although the particles of solids are fixed at their positions, they vibrate constantly.
