The process of changing water from one state to another involves the addition or removal of energy, commonly known as heat.
When ice is exposed to heat, its temperature increases until it reaches the melting point of 0°C. At this point, the ice begins to change from a solid to a liquid state, known as melting. The heat energy absorbed by the ice during the melting process is used to break the intermolecular bonds between the water molecules in the ice, allowing them to flow more freely and become a liquid.
When water is further heated beyond its melting point, it reaches its boiling point of 100°C. At this temperature, the water molecules gain enough energy to break the bonds holding them together in a liquid state and transform into water vapor, a gaseous state. This process is called vaporization. The heat energy taken in by the water during vaporization is known as the latent heat of vaporization.
The opposite processes occur when water vapor or liquid water lose heat energy. When water vapor cools, it reaches its dew point, where it begins to condense back into liquid water. This process is called condensation. The heat energy released during this process is known as the latent heat of condensation.
Finally, when liquid water cools below its freezing point, it begins to solidify and become ice. This process is known as freezing, and the heat energy released during this process is known as the latent heat of fusion.
Overall, the changing states of water involve the gain or loss of energy, through melting, boiling, condensation, and freezing.
