Yes, gas molecules do move freely in three directions.
(Every substantial particle is to be found in "space" = "3D" = three "dimensions", but not essentially "moving free")
A gas is a collection of molecules or atoms that move about freely in all directions. They have high kinetic energy and are continuously colliding with each other and the walls of their container, creating pressure.
Gas is the form, there is no form of gas, the particles in gas move freely, they actually vibrate.
In a solid, atoms vibrate in fixed positions due to strong bonds between them. In a liquid, atoms move more freely than in a solid, constantly rotating and moving past each other. In a gas, atoms move rapidly in random directions, colliding frequently with each other and the container walls.
solid and gas differ from each other simply because their atoms are differrent in composition.Atoms of a solid is compacted to each other.While the atoms of a gas are far apart from ech other sothat it can move freely. Dominique Odencia
It seems like you are looking for "gas". Atoms in a solid vibrate at very high frequencies (but I wouldn't consider that "moving" in the general sense), and atoms in a liquid vibrate at close to the same frequency but move around and past each other, though not as fast as in a gas.
Yes
A gas is a collection of molecules or atoms that move about freely in all directions. They have high kinetic energy and are continuously colliding with each other and the walls of their container, creating pressure.
When atoms gain enough energy to be able to move freely and independently, the matter has changed into the state of a gas. In the gas state, atoms are not fixed in a specific position and can move and interact with other atoms more freely compared to in solid or liquid states.
Yes. Every kind of matter is made up of atoms.

Gaseous state. Atoms in this state have enough thermal energy to overcome their intermolecular forces, allowing them to move freely and independently of each other.
Democritus
Gas is the form, there is no form of gas, the particles in gas move freely, they actually vibrate.
In a solid the atoms are tightly packed together and vibrate in place, in a liquid the atoms are loosely packed together and can move past each other, and in a gas the atoms are far apart and move freely and collide frequently.
the amount of energy they have. In a solid, atoms are tightly packed and vibrate in place. In a liquid, atoms are closer together but can move past each other. In a gas, atoms are far apart and move freely.
Gas as the particles move freely of one another.
Atoms are in the gaseous state when they fly around freely. In this state, atoms have enough energy to overcome the forces that hold them together in a solid or liquid, allowing them to move independently and rapidly throughout the space they occupy.
