Chemistry=> State of matter=>Change of State
We have three states of matter, the state of matter of a substance will depend on how the molecules are arranged.
In a solid, the molecules are close together, the solid will maintain its shape regardless of the container where it is, and its density is high because there will be more mass in less volume.
In the gaseous state, the molecules are far apart from each other, the liquid state is an intermediate level. The gas and the liquid will tend to occupy the shape of the container, with the difference that the gas will occupy the entire available volume.
Gas is highly affected by pressure change, which means that is Highly compressible.
Therefore, from the given options we can say:
No definite shape ---> Gas, liquid
Highly compressible ---> Gas
Definite volume ---> Solid, liquid
Low density ---> Gas
