7. Particle Theory
7.1 States of Matter, Kinetic molecular theory
Explore States of Matter and Kinetic Molecular Theory
You will discover how tiny particles in constant motion explain everything from why ice melts to why perfume spreads across a room.
What You'll Learn
You learn all matter consists of tiny constantly moving particles.
You discover solids, liquids, and gases differ in particle arrangement.
You understand temperature increases particle kinetic energy and speed.
You apply particle theory to explain diffusion and evaporation observations.
What You'll Practice
1
You will identify states of matter from described particle behaviours.
2
You will explain evaporation and diffusion using kinetic molecular theory.
3
You will answer questions about particle energy, spacing, and motion.
Why This Matters
Understanding kinetic molecular theory gives you the scientific tools to explain everyday phenomena from melting ice to spreading smells and prepares you for advanced topics in chemistry and physics.
