Takes the shape of the container?
Gases do not have a definite volume, which means that they can be expanded and compressed, depending on the pressure the gas is under. Gases also do not have a definite shape, so they take the shape of whatever container they are in. Unlike gases, liquids do have a definite volume because they are not easily compressed. However, like gases, liquids take the shape of their container, too. Solids have definite volume and definite shape.
