Answer: Option (b) is the correct answer.
Explanation:
In liquids, molecules are closer together as compared to molecules of a gas. As molecules of a liquid are held by less strong forces of attraction.
Hence, these molecules have some kinetic energy due to which collisions occur between them.
Since, there are gaps present between molecules of a liquid. Therefore, they have definite volume but no definite shape.
On the other hand, molecules of a gas are held together by weak intermolecular forces. Hence, they have very high kinetic energy and more number of collisions take place between them.
Gases do not have a definite shape and they occupy whole volume of a container in which they are kept.
In solids, molecules are held together by strong intermolecular forces of attraction. Hence, they are not able to move from their initial place and thus they have definite shape and volume.
Therefore, we can conclude that the statement they are closer together and slower moving than the particles in a gas, is generally true about the particles in a liquid.
