(b) the particles of matter attract one another
(c) the particles of some of the matter are moving constantly
(d) the particles of all the matter have spaces between them

Answer 1

(c) 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.
