Physics paper 1 - Coggle Diagram

- - - - Held together by a strong forces of attraction and vibrate around their position
    - - The intermolecular forces are too weak to keep the particles in a fixed position so they are free to move
    - - The particles are in constant random motion as there are very weak forces between them
  - - - Melting
    - - Evaportation
    - - Condensation
    - - Freezing
  - - - They also have potential energy stores
        
        as the particles move further apart, their potential energy stores will increase
  - - - Increasing interanl energy
        
        Energy is being used to break intermollecular bonds
    - - Decreases internal energy
        
        Energy is being used to form intermollecular bonds
- - - - Negative charge
    - - Positive charge
    - - No charge
    - - Number of protons is equal to the number of electrons
      - Neautral
