The diagram shows the changes in state of water (H2O). What is the process Y called?FreezingEvaporationMeltingBoiling

To determine what process Y represents in the changes of state of water, we must analyze the options provided: Freezing, Evaporation, Melting, and Boiling.

1. Understanding the Processes:

   • Freezing: The transition of water from a liquid to a solid state (ice).
   • Evaporation: The transition of water from a liquid to a gaseous state (steam).
   • Melting: The transition of ice from a solid to a liquid state (water).
   • Boiling: The transition of water from a liquid to a gaseous state at its boiling point.

2. Identifying Process Y:

   • Since the question asks specifically for process Y in a diagram depicting the changes in state of water, we identify the context of the diagram.
   • For instance, if the process Y shows a transition where solid water (ice) turns to liquid water, it would be called Melting.
   • Conversely, if the diagram represented liquid water becoming ice, it would be Freezing.

3. Conclusion:

   • If the diagram indicates a decrease in temperature leading to a transition from liquid to solid, then that would be Freezing. If it indicates an increase in temperature from solid to liquid, the process would be Melting.
   • In absence of the visual diagram here, we can conclude appropriately based on typical representations.

Final Answer

If process Y indicates water turning to ice, it is Freezing; if it indicates ice turning to water, it is Melting.
