Solid (Ice)
* Strongest attraction: Water molecules in ice are held together by a strong network of hydrogen bonds. These bonds form because the oxygen atom in one water molecule has a partial negative charge, while the hydrogen atoms have a partial positive charge.
* Ordered structure: The hydrogen bonds create a highly ordered, crystalline structure where molecules are tightly packed and have limited movement.
Liquid (Water)
* Weaker attraction: As the temperature increases, the hydrogen bonds in ice begin to break. This weakens the attraction between water molecules, allowing them to move more freely.
* Less ordered structure: Water molecules in liquid form are still attracted to each other, but the bonds are constantly breaking and reforming, creating a more disordered, fluid structure.
Gas (Water Vapor)
* Weakest attraction: In the gaseous state, the energy of water molecules is high enough to overcome almost all attractive forces. The hydrogen bonds are broken completely, and the molecules move independently with little interaction.
* No defined structure: Water molecules in the gas phase are far apart and move randomly, with no defined structure.
In summary:
* Solid to Liquid: The energy input breaks some hydrogen bonds, causing a decrease in the strength of attraction between water molecules, leading to a more disordered structure.
* Liquid to Gas: Further energy input breaks all hydrogen bonds, causing the attractive forces to become negligible, leading to a completely disordered structure with molecules moving independently.
