A theory explaining matters behavior based on molecular motion and interactions

Kinetic molecular model

The key concepts of KMM

Molecules in motion Kinetic energy Particle interactions

How does KMM explain solids, fixed shape, and volume?

Particles vibrating fixed positions because of strong intermolecular forces

Why are solids denser than liquids?

Tightly parked particles leave little spaces

Why are liquids incompressible but take the shape of their container

Particles are close and slide past each other

What determines viscosity and surface tension and liquids

Intermolecular forces affecting particle movement

How does temperature affect particle motion?

Higher temperatures increase kinetic energy

What happens to particles during face changes?

It increases kinetic energy, breaking bonds, and changing states

Five postulates of KMT

Constant particle motion Small particle size relative to distance Elastic collision Kinetic energy Proportional to temperature No significant forces except during collision

Real world example of KMM

Hot air balloon rise as heated, gas expands, and becomes less dense

Why does ice float in water?

Solid water is less dense

Gases are compressible because particles are far apart

Gas compression

What activity demonstrates face changes

Heating ice to observe its transition to liquid

Why do balloons expand in hot water?

Gas molecules, move faster, and spread out when heated
