Question

Why are the gases highly compressible?

Answer 1

Gas:

• Gas is a state of matter which has only definite mass but no definite shape and volume.
• It takes up the shape of the container.
• The molecules can movable throughout the container

e.g. — $\mathrm{Carbon}\mathrm{dioxide}\left({\mathrm{CO}}_2\right)$, $\mathrm{Oxygen}\left({\mathrm{O}}_2\right)$, etc.

• The gases are highly compressible because the molecules can movable throughout the container, have move amount of free space and less dense than other states of matter.
• In otherwords, the intermolecular space between the gas particles is very large as compared to the intermolecular space between the liquid and solid particles.
• Hence, gases are more compressible.
