🌡️ Phase Changes

Explore the transitions between solid, liquid, and gas states of matter

Difficulty: ● Medium

SOLID
📐 Phase Transitions
Melting: Solid → Liquid
Energy increases, bonds weaken (0°C for water)
Vaporization: Liquid → Gas
Energy increases, particles escape (100°C for water)
Condensation: Gas → Liquid
Energy decreases, particles slow down
Freezing: Liquid → Solid
Energy decreases, ordered structure forms
📚 Key Concepts
  • Solid: Fixed shape, vibrating particles in lattice
  • Liquid: Takes container shape, particles flow freely
  • Gas: Fills entire volume, particles move rapidly
  • Phase changes occur at specific temperatures
  • Higher pressure can change phase transition points
🔬 Try This
  • Slowly heat from -50°C to 150°C - watch transitions
  • Observe particle spacing in each phase
  • See how pressure affects the container volume
  • Compare particle speeds in different phases
  • Try rapid heating vs. slow heating
