Particles and states of matter

• Changes of state


  1. Evaporation

  2. Melting

  3. Add energy

  4. Loiting

  5. Melting

  6. Freezing

  7. Evaporate

  8. Condensation
• Boiling point


  The temperature where a liquid becomes a gas
• Melting point


  The temperature where a liquid becomes a solid
• When a solid is heated


  1. It gains more energy

  2. The particles start to move more

  3. That's called melting
• Diffusion


  The movement of particles from an area of high concentration to lower concentration
• Particles are spreading out
• Factors that affect the rate of diffusion


  • Temperature
  • Distance
  • Liquid or gas
• Elements are the simplest type of substance, they cannot be broken down into any other type of substance
• We can combine different elements to make new substances
