Explanation:

In a solid, the particles are held tightly together as possible in a neat and are arranged in order.

The particles are strongly held together so as to allow movement from place to place but the particles vibrate about in their fixed position in the structure.

When there is heat or no heat, the particles are moving so slowly that the atomic attractions result in bonds that are so difficult to break without adding energy.
