What occurs at stage A?
Water cools and turns to liquid
Water becomes runoff or groundwater
Water vapor clumps around dust particles
Water evaporates from surfaces

the answer is water evaporates from surfaces

Answerδh > 0explanationc₆h₆  (s)  → c₆h₆ (l)if you are changing it from a solid to a liquid, you are pretty much melting the solid. this requires heat energy. therefore, the reaction is endothermic (takes in energy); the system enthalpy increases as the reaction proceeds: δh > 0.
