Step-by-step explanation:
An object whose particles are held by strong intermolecular forces of attraction is known as a solid substance.
In solids, particles have least kinetic energy and they can only vibrate at their position.
Therefore, solids have a definite shape and volume.
Hence, when we place a solid object in a container then it is unable to take the shape of container because its molecules are held strongly with each other.
Thus, they bond between its molecules cannot be broken down easily.
