Answer: Option (B) is the correct answer.
Explanation:
In solids, molecules are held together by strong intermolecular forces of attraction. Hence, the molecules are much more closer to each other.
As a result, they are unable to move from their initial position and can only vibrate at their mean position.
Hence, a solid has definite shape and volume. Solids cannot be compressed.
Whereas in a liquid, particles are held by less strong intermolecular forces of attraction as compared to solids. Therefore, in a liquid molecules are able to slide past each other and thus, they can be slightly compressed.
Liquids do not have a fixed shape but they do have a fixed volume.
In gases, molecules are widely spread out as they are held by weak Vander waal forces. Hence, they do not have a fixed shape but they acquire the volume of container in which they are placed.
Thus, we can conclude that the statement its particles are packed together tightly, is correct.
