Matter that has neither a definite volume nor a definite shape is in the________ state
Correct Answer
gaseousExplanation
Matter that has neither a definite volume nor a definite shape is in the gaseous state. In the gaseous state, the particles of matter are spread out and move freely, filling up the space available to them. Unlike solids and liquids, gases do not have a fixed shape or volume, as they can expand or contract to fit their container.
