Answer:
As matter is made up of discrete units i.e atoms and having subatomic particles. The state that makes matter is continuously in motion.
Step-by-step explanation:
- As in water particles can move slides pas one another and have little frees spaces. In liquids, particles are quite close to each other and move in random motion. Example of waves, currents.
- With an increase in temperature, the particles move faster as they collide with each other due to the kinetic energy. In solids, particles move or vibrate in the position of their structure. Even at lower temperatures and have no fixed positions.
- As a river does not crease to be river due to its flows. This flow is what makes a river what it is. The universe, earth, stars, and galaxies are in a constant state of motion
