Gasses are highly compressible because it is less dense than other states of matter. it's intermolecular force of attraction is less and it has more space between the molecules. Therefore, it is easy to compress gas.
While, solids are almost incompressible. This is because the intermolecular force of attraction in solids is greater compared to other states of matter. The moles in solids are tightly packed. Therefore, solids are almost incompressible.

Gases are highly compressible because their molecules are very tightly packed.
This statement is false. Gases are highly compressible, but not because their molecules are tightly packed. In fact, the molecules in a gas are widely spaced compared to liquids and solids.
Explanation:
1. Gas molecules and their arrangement:
In a gas, the molecules are in constant random motion. They are not held together in a regular pattern like in solids or liquids. The molecules are widely spaced and move freely, which is why gases have low densities compared to solids and liquids.
2. Mixing of gases:
Gases mix evenly and uniformly without any mechanical aid. This is due to the random motion of gas molecules. As the molecules move around, they collide with each other and mix together. This property of gases allows them to spread out and occupy the entire volume of the container they are placed in.
3. Pressure exerted by gases:
The pressure exerted by gases on the walls of the container is equal in all directions. When gas molecules collide with the walls of the container, they exert a force. This force is distributed evenly in all directions, resulting in equal pressure on all sides of the container. This is known as the principle of Pascal's law.
4. Compressibility of gases:
Gases are highly compressible because the molecules are not tightly packed. Unlike solids and liquids, the intermolecular forces in gases are very weak. As a result, gas molecules can be easily compressed into a smaller volume by applying pressure. When pressure is applied, the gas molecules are forced closer together, reducing the volume they occupy.
Conclusion:
In summary, the false statement is that "Gases are highly compressible because their molecules are very tightly packed." Gases are highly compressible because their molecules are widely spaced and can be easily brought closer together by applying pressure.
