gaseous state
Matter without shape
The gaseous state is one of the three classical states of matter, along with solid and liquid.
In this state, molecules move freely and expand to fill any container, with no fixed shape or volume.
Water enters the gaseous state as steam or vapor.
Matter in the gaseous state is highly compressible.
