Changes in State - Coggle Diagram

- - - - As the temperature increases, the particles usually have more kinetic energy.
  - - - The chemical potential energy of particles increases and decreases as the distances between particles increase or decrease.
- - - - The opposite is true when you remove thermal energy. If enough thermal energy is added or removed, a change of state can occur.
- - - - By adding thermal energy to the aluminum, we can increase the temperature of the aluminum until it reaches the melting point of which it then melts. While it is melting, the temperature doesn't increase (however, energy changes still occur,) and it turns into liquid.
        
        Energy Change: When a solid melts into a liquid, its temperature doesn't change, but the energy changes. This is because the particles don't speed up, but they move farther apart. Then after it melts, they start to speed up because of the thermal energy.
    - - After the aluminum melts, it is poured into molds to cool. Freezing is the opposite of melting and there is a freezing point. As the aluminum cools, the thermal energy leaves it.
- - - - Boiling occurs when thermal energy is added to water until it reaches its boiling point, which then the particles move farther apart until they no longer have any attractive force.
        
        If thermal energy continues to be added, then after it becomes a gas, the temperature keeps increasing.
        
        Condensation
        
        Condensation is when gas turns into liquid because it looses too much thermal energy.
    - - Evaporation is vaporization that only occurs at the surface of a liquid.
