When water evaporates from Earth’s surface into the atmosphere, its molecules enter the gas state. What subsequent change causes gas molecules to condense into the small water droplets that form clouds? A. Mass is reduced.
B. Volume is increased.
C. Temperature is reduced.
D. Pressure is increased.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
