    Big Ideas about Phase Change Big Ideas about Phase Change Presentation Transcript

    • Big Ideas about Phase Change
    • Phase changes happen...
        • Between the three states of matter:
          • Solid, Liquid and Gas
        • 4 Types of Phase Changes:
          • Melting
          • Freezing
          • Evaporation
          • Condensation
    • The key to starting a phase change....
        • HEAT!
        • More Heat = More Kinetic Energy
        • More Kinetic Energy = More Particle Movement
    • Particles and Kinetic Energy
      • When particles have more kinetic energy:
        • more speed
        • hit other particles harder
        • hit other particles more often
        • Expand
      • When particles have less kinetic energy:     
        •   less speed
        • hit other particles less and not as hard
        • Contract
    • Let's Compare Phase Changes
      • Melting - Solid to a Liquid
        • Caused by heat
        • heat = kinetic energy
      •  
      •  
      •  
      • Evaporation- Liquid to a Gas
        • Caused by heat
        • Heat = kinetic energy  
      • Condensation - 
      • Liquid to a Gas
        • Caused by cooling
        • Particles slow down & contract
      •  
      • Freezing - Liquid to a Solid
        • Caused by cooling
        • Particles slow down & contract  
    • Melting & Evaporation Caused by heat---
    • Condensation    &     Freezing   Caused by cooling & contracting
