Explanation:

Solid, liquid and gas are the three types of matter. In solid, the molecules are tightly packed together. The intermolecular forces is very strong and the particles do not move from one place to another. The particles are so closely packed that they move at their own place and vibrate forth and back. The motion of the movement of the particle and its force are the two factors that help in determining the state of matter.
