1. KINETIC MOLECULAR THEORY
Provides explanation for different states of matter at the molecular level.

2. Matter is composed of tiny particles called atoms or molecules.
Gold atoms

3. These particles are always undergoing rapid and constant random movement (Brownian motion). The collisions between the particles are elastic.

8. Continuous evaporation taking place in an uncovered container
Continuous evaporation taking place in an uncovered container. In the covered container, a state of dynamic equilibrium (liquid-to-gas-to liquid) exists.
