Answer :

Answer: TRUE, The particles of gas move freely within the whole space of any container  

Explanation:

we know that there are three types of matter:- SOLID, LIQUID and GAS in which the molecules/particles of solid matter are compactly packed resulting in minimum allowance for the movement of its particles, accordingly gas allows maximum allowance for the particles to move as its particles aren't compactly packed and hence particles of gas are able to move freely even within the whole space of any container.
