they all contract.
I can only tell you that gases are does not have a difinite shape and volume . E.g air / nitrogen / carbon dioxide / water vapour / . . .
ANSWER unlike solids, both liquids and gases can change their shape to fit the container in which they are held. however, gases can also change volume unlike liquids.
Solids and liquids are difficult compress. Gases, however, are easy; they respond to changes in temperature and volume.
expand
-- Gases change their shape and volume to match the container they're in. -- Liquids change their shape but not their volume. -- Solids don't change anything. It doesn't matter if they're in a glass jar, a rubber balloon, or a paper bag. ===== A Gas
solids and liquids
Structure. Solids have definite shape and definite volume. Liquids have definite volume but indefinite shape. Gases have both indefinite shape and indefinite volume.
Solids ---heat---> Liquids ---more heat---> gases
Solids have a set volume. Liquids have a set volume. Gases do not have a set volume. Why? Solids are solids. They don't move. They're in a 'frozen state' as is. Liquids 'mold' to the shape of their container and they stay there. Gases are free to go anywhere. Always moving and 'flying.'

Solids are usually more dense because solids have a smaller volume than liquids or gases, so the same amount of mass is in a smaller volume, making the density greater.
they are compromised.
Unlike solids and liquids, a gas will expand to fill the space available to it.
Yes they do. Liquids have no fixed shape and gases have no fixed volume.
the volume of them all stay the same

Solids have a definite shape and volume. Liquids have a definite volume, but no definite shape - they take the shape of their container. Gases have no definite volume and no definite shape - they expand to fill their entire container.
