Ink Spreading: Demonstrating Particle Movement
When a drop of ink is placed in water, it naturally spreads out and mixes with the water over time, even without any external force like stirring. This process is called diffusion.
Diffusion and Particle Motion
Diffusion occurs because the tiny particles that make up both the ink and the water are in constant, random motion. They move around, collide with each other, and spread out into available space.
Conclusion on Matter Particles
The observation of the ink spreading evenly demonstrates that particles of matter are constantly moving. This movement causes the ink particles to disperse throughout the water until they are uniformly distributed, leading to the even spread.
Therefore, the phenomenon illustrates the principle that matter is composed of particles that are always in motion.
The correct option is: Particles of matter are constantly moving.
