What characterizes a gas state of matter?

Definite shape and volume
Definite volume but no definite shape
No definite volume but definite shape
No definite volume or shape

The correct answer is: No definite volume or shape

A gas state of matter is characterized by having no definite shape or volume. This means that gas particles are free to move in any direction and fill any container that they are in, as they do not have any attraction to each other. This is what sets gases apart from solids and liquids, where particles have a definite shape and volume due to strong intermolecular forces. Therefore, options A, B, and C are incorrect as they mention either a definite shape or volume, which are not characteristics of a gas state.
