Step-by-step explanation:
Solids are the species that contain particles with strong electrostatic force of attraction. As a result, particles are much more closer to each other and unable to move easily from their initial place.
Hence, solids occupy definite shape and volume.
Whereas in liquid state, particles are held slightly lose as compared to in solids. As a result, particles of a liquid are able to slide past each other and they have a fixed volume as they occupy the shape of container in which they are poured.
Thus, we can conclude that solid phase of matter consists of particles that are locked into place and unable to move past each other.
