Final answer:
The process of the forming of water vapor is best described by water absorbing energy and transitioning from a liquid to a gaseous state at the heat of vaporization point.
Step-by-step explanation:
Which describes the process of the forming of water vapor? The process described by the forming of water vapor is B) At the heat of vaporization point, absorbed energy changes water from a liquid state to a gaseous state. Vaporization, also known as evaporation when it occurs below the boiling point, is an endothermic process that requires the addition of heat to break the intermolecular interactions between molecules. As liquid water heats up, hydrogen bonding makes it challenging to separate the water molecules, necessitating a significant amount of energy, referred to as water's heat of vaporization, to transition into the gaseous phase.
When water reaches its boiling point, the heat is finally able to break these hydrogen bonds, allowing the water molecules to escape from the liquid as a gas. Individual water molecules can also acquire enough energy to engage in evaporation even when below the boiling point. In summary, the correct description of the process of water turning into vapor is the absorption of energy by liquid water and its transition into a gaseous state at the heat of vaporization point.
