1. Properties of Particles in Motion Constant Motion, Spaces, Attraction, and Effects of Temperature

2. Particles Are Constantly in Motion • All matter is made up of tiny particles. • These particles are always moving, even in solids, though movement is more restricted in solids. • Example: The particles in gas move freely, while in solids, they vibrate in place.

3. Spaces Between Particles • Particles in matter are not tightly packed; there are spaces between them. • The amount of space depends on the state of the matter (solid, liquid, gas).

4. Attraction Between Particles • Particles attract each other with a force that varies depending on the distance between them. • The stronger the attraction, the closer the particles are (solids).

5. Effect of Temperature on Particle Motion • When temperature increases, particles move faster. • Heat causes particles to gain energy, leading to increased movement and expansion.

6. Real-World Example: Boiling Water • As water heats, particles move faster, causing it to change from liquid to gas (steam).

7. Summary Particles are always in motion. There are spaces between them. They attract each other. Heat increases particle motion.
