Properties

Solid

Gas

Shape and volume

Has fixed shape and fixed volume

Has no fixed shape but takes the shape of a container and has a fixed volume

Has no fixed shape and no fixed volume but takes the shape of any container

Motion

molecules vibrate on their position and do not move from one place to another

Molecules move and slide pass one another

Molecules can move pass one another, they are freely moving

Compressibility

Not easily compressible because of very little space between particles

Not easily compressible because of very little space between particles

Compressible because of a lot of free space between particles

Flow rate

Does not flow easily because particles are rigid

Flow easily since molecules can move slide pass one another

Flow very easily since molecules can move pass one another

Force between molecules

Very strong

Weak

Very weak or negligible
