gaseous
Neither liquid nor solid
Gaseous describes matter in the state of a gas—neither solid nor liquid—where molecules move freely and expand to fill any container.
The gaseous emissions from the plant raised environmental concerns.
By extension, gaseous can describe something insubstantial or lacking solidity: His gaseous promises never materialized into action.
