In liquids, molecules particles are close together but move in random directions.
In solids, they are closely packed together and they vibrate a little.
In gases, they love around really quickly and are farther apart (even more than liquids).
The weight of the box is 50x9.8 = 490 N. The force of friction is 100N. F= μΝ so coefficient = 100/490 = 0.20
