Particulate Nature of Matter
↓
7.1 What Is Matter Composed of?
Constituent particles
Tiny particles
Too small to see
Interparticle spaces
Gaps between particles
7.2 What Decides the States?
Interparticle attractions
Solid
Fixed shape and volume
Liquid
Fixed volume, no shape
Gas
No fixed shape or volume
7.3 Interparticle Spacing
Solid < liquid < gas
Compressibility
Gases compress, liquids don't
7.4 How Particles Move
Particles in constant motion
Thermal energy
Decides the state of matter
