Sagot :

Answer:

b. the water molecules gain heat energy and evaporate

Answer: B

Explanation: Because Water molecules on the surface of liquid water are evaporating into air at the same time that water molecules in the air are condensing onto the liquid water. In order for the liquid water to completely evaporate away, thus leaving the clothes dry, water molecules must leave the surface more quickly than they return.
