What characterizes the gas state of matter?

Fixed volume and fixed shape
Fixed volume but no definite shape
No definite volume nor definite shape
Fixed shape and variable volume

The correct answer is: No definite volume nor definite shape

The gas state of matter is characterized by having no definite volume and no definite shape. This distinction arises from the behavior of gas molecules, which are widely spaced and move freely and rapidly in all directions. Because of this movement, gases can expand to fill any container they occupy, taking on the shape and volume of that container. This allows gases to flow easily and to be compressed. In contrast, other states of matter, such as solids and liquids, exhibit different characteristics; solids have both fixed shape and fixed volume, while liquids have a fixed volume but can take the shape of their container. The understanding of these properties helps in distinguishing between the different states of matter and their behaviors under various conditions.
