What is the name of the process when energy is removed from water vapour and the gas becomes liquid water?

Question

BlackTom AI · Accepted Answer

In this question, we're asked to identify the phase change that occurs when energy is removed from water vapour and it becomes liquid water.
First, consider what happens to a gas (water vapour) when energy is extracted from it: the molecules lose kinetic energy, move more slowly, and come closer together until they form a liquid. This process is known as condensation, which is precisely the gas-to-liquid transition driven by cooling or energy removal.
If we imagine other common phase-change options for water, they would be: evaporation or boiling (gas becomes liquid water when energy is added to a liquid to form a gas), freezing (liquid becomes solid water when further energy is removed), and sublimation (solid becomes gas without becoming liquid under suitable conditions). Each of these describes a different direction of energy transfer and a different phase change than condensation.
In short, condensation is the term that accurately describes removing energy from water vapour to yield liquid water, whereas the alternative processes involve different initial/final phases and energy directions.
Note: the provided data lists the answer as Condensation, and no alternative answer choices were supplied to compare directly. The reasoning above aligns with the standard phase-change knowledge for water.
