Because the attraction between gas molecules is negligible so its easy for gas molecules to move free
fast and with freedom
Gases have the maximum intermolecular space among the three states of matter (solid, liquid, gas). This is because gas particles are far apart and have weak forces of attraction between them, allowing them to move freely and occupy a larger volume.

Diatomic gases have more degrees of freedom. They are also larger in size and mass. specific heat is proportional to the number of degrees of freedom; monatomic gases can only move linearly and have 3 degrees of freedom, molecules can also rotate and vibrate, so have more degrees of freedom.
When a gas expands into a vacuum, the entropy of the gas increases. This is because the gas molecules have more freedom to move around and occupy a larger volume, leading to a more disordered state and higher entropy.
Molecule movement is the smallest in a solid. In a solid, the molecules are closely packed and have limited freedom to move and vibrate. In liquids and gases, the molecules have more space and freedom to move, resulting in greater molecular movement.
The maximum volume of gas that can be stored in a standard gas cylinder is typically around 50 liters.
In the gas state, water molecules move the fastest due to the higher kinetic energy they possess compared to the liquid or solid states. In the gas phase, water molecules are further apart and have more freedom to move around, resulting in higher speeds.
The phase with the most energy is the gas phase. Gas molecules have higher kinetic energy compared to solid or liquid molecules because they have more freedom to move and collide with each other at higher speeds.
The correct order of matter from slowest to fastest that molecules or particles move is: solid, liquid, gas. In a solid, particles are tightly packed and have the least amount of movement. In a liquid, particles have more freedom to move around. In a gas, particles have the most kinetic energy and move the fastest.
Minimum Government, Maximum Freedom
In general, gases have higher velocities than liquids due to their weaker intermolecular forces and greater molecular freedom to move around in a container. This allows gas particles to move faster and spread out to fill the available space. Liquids have lower velocities because their molecules are more closely packed and move more slowly than gas particles.
